Follow Two Baby Florida Box Turtles

In August 2013, two Florida box turtle hatchlings called Popeye and Pinto Bean walked out of a clutch of eggs nobody knew had been laid. Their keeper had not seen the mother mate, had not seen her dig, and only found the babies by accident on a warm Florida morning. The blog that followed them — Tiny Turtle Journey — became one of the best non‑academic records of hatchling Terrapene carolina bauri growing up in captivity that I have ever read. This is what their story can teach you about raising baby Florida box turtles, and why hatchlings are not just small adults.

By Maya, with field notes from Hannah on wild Florida bauri populations.

The Florida box turtle, in 90 seconds

The Florida box turtle (Terrapene carolina bauri) is one of four widely recognised subspecies of the common box turtle, restricted to peninsular Florida and the Florida Keys. Adults are small — typically 11–14 cm carapace length — with a tall, often almost helmet‑shaped shell, a dark base colour, and bright yellow radiating lines on each scute. They have three claws on each hind foot, which is a quick field tell against the Eastern and Gulf Coast subspecies. They eat almost anything, swim better than people expect, and they are extraordinarily long‑lived.

In the wild they are listed as Vulnerable on the IUCN Red List like the rest of Terrapene carolina, and the Florida Fish & Wildlife Conservation Commission classifies them as a Species of Greatest Conservation Need. Possession is regulated and wild collection is restricted — if you are reading this and considering taking a bauri off a Florida road, please don’t, and please check the FWC’s wildlife regulations before you do anything else.

What Popeye and Pinto Bean’s story really showed

The Tiny Turtle Journey blog (originally at tinyturtlejourney) ran weekly photo updates and care notes from the day the hatchlings emerged through their first full year. The thing that makes that record so valuable is not the cute pictures — there are plenty of cute box turtle pictures online — but the specificity. Daily soak schedules. Substrate moisture readings. The exact week each turtle figured out that worms were food. Weights, in grams, week over week.

If you have only ever read adult box turtle care sheets, hatchling care is going to surprise you. Here is what their first year demonstrated, condensed into the lessons that matter.

1. Humidity is not a setting, it is a habit

Adult Florida box turtles do fine at 60–70% ambient humidity if they have a moist hide and a soaking dish. Hatchlings do not. A 10‑gram baby has so much surface area relative to its body mass that it dehydrates in hours, not days. Popeye spent his first month in an enclosure where moss substrate was kept consistently damp (not wet, not muddy — damp enough to clump when pinched), with humidity readings of 80–90% on a calibrated digital hygrometer.

The keeper soaked both hatchlings in shallow lukewarm water for 15–20 minutes every single day. Not because they were dehydrated — because daily soaks are how you make sure they never become dehydrated. We do the same thing with every Terrapene hatchling we have ever raised. Skipping soaks is the single most common cause of hatchling mortality we see.

2. UVB exposure starts on day one

One of the cleanest patterns in the Tiny Turtle Journey records was the difference in growth between the first six weeks (low UVB exposure while the keeper was figuring out lighting) and the months after a proper T5 HO UVB fixture went in. Shell growth visibly accelerated. Pinto Bean’s scutes thickened. There was no MBD, no soft shell, no pyramiding — and that is not luck.

For hatchling Florida box turtles we use a 6% T5 HO UVB tube (Arcadia or Zoo Med ReptiSun), positioned 25–30 cm above the basking spot with no glass or mesh in between, on a 12‑hour daily cycle. Replace the tube every 12 months even if it still glows — UVB output collapses long before visible light does. Hannah, who works with wild bauri counts, has the same rule for any temporary rehab enclosure.

3. Temperature gradients, not “warm enclosures”

“Keep your box turtle at 75–85°F” is the lazy version of the advice. What you actually want is a basking spot at around 85–90°F (29–32°C), a cool end at 70–75°F (21–24°C), and the freedom for the turtle to choose. Florida bauri are the most tropical of the carolina subspecies and tolerate the warm end well, but they still need to thermoregulate, which means choice. Popeye’s enclosure had a halogen basking lamp at one end and a hide at the other; the keeper logged where each turtle was at 9 am and 4 pm every day for the first three months, and that data is the best argument I have ever seen for a gradient over a setpoint.

4. Diet: live, varied, dusted

The Tiny Turtle Journey notes show a hatchling diet that was probably 70% animal protein for the first six months, tapering toward the 50/50 omnivore mix adults need. That is the right shape. Worms, slugs, isopods, soft‑bodied insects, the occasional pinky head of a dead pinky mouse — all alive, all calcium‑dusted three feedings a week, all multivitamin‑dusted once a week. Plant matter was offered every day even when ignored; both hatchlings started picking at strawberries and mushrooms around month four. (For the full adult version of this, see our Box Turtle Diet guide.)

The two things to avoid: iceberg or romaine lettuce as a staple (mostly water, almost no nutrition), and any feeder insect that came out of your garden if your garden gets pesticide. We have lost a hatchling to neonicotinoid exposure through wild‑caught earthworms, and it was not pleasant.

5. Hatchlings should not hibernate their first winter

This one is non‑negotiable for us. A first‑winter hatchling does not have the fat reserves or kidney maturity to survive a true brumation cycle, and the data on hatchling mortality through artificial hibernation is grim. Tiny Turtle Journey kept Popeye and Pinto Bean active and feeding through their first winter, with full lighting and warmth, and only introduced a partial cooling cycle their second autumn. We do exactly the same thing — see our forthcoming box turtle hibernation guide for the full breakdown of when to start and how to do it.

6. Predators, escape, and the boring infrastructure

A box turtle hatchling can climb anything that has a corner. They can squeeze through gaps you would have sworn were too small. They are the right size for a rat, a corvid, a domestic cat, or a wandering toddler to view as a toy. Outdoor enclosures for hatchlings need a fully closed top (galvanised hardware cloth, not chicken wire), sunken walls 15 cm into the substrate, and supervision. Indoor enclosures need lids. The Tiny Turtle Journey blog has at least one entry that begins “I cannot find Pinto Bean” and ends with the turtle wedged behind a bookcase.

7. They imprint on routine, not on you

Box turtles are not affectionate. They will learn the rhythm of your feeding schedule and meet you at the front of the enclosure at the right time, and that is the closest thing to bonding you are going to get. Both Popeye and Pinto Bean learned, within their first three months, that the wet whoosh of the soaking bowl being filled meant warm‑water time. They walked to it. That is not love — that is conditioning. Enjoy it for what it is.

If Tiny Turtle Journey is offline

The original blog has been intermittently available over the years. If you cannot reach it, the Wayback Machine has the 2013–2014 posts archived, and the photos are worth the trip. We have linked to substantive species, husbandry and conservation pages elsewhere on Box Turtles where the equivalent material now lives.

Quick reference — Florida hatchling care sheet

For anyone who wants the one-page version of everything above:

• Substrate: damp sphagnum + coco-coir + leaf litter blend, never bone dry, never waterlogged. Spot-check moisture every morning.
• Humidity: 80–90% ambient on a calibrated digital hygrometer (not the pet-shop dial gauge). One persistently moist hide essential.
• Temperature: basking 29–32°C, cool end 21–24°C, night drop to 18–21°C. Gradient is the point, not any single number.
• UVB: T5 HO 6% (Arcadia ProT5 or Zoo Med ReptiSun 5.0), 25–30 cm above basking, no glass between the tube and the animal, replace every 12 months.
• Soaking: 15–20 minutes in shallow lukewarm water daily for the first six months, then 3–5× weekly. Use the same water bowl every time — they recognise it.
• Diet: 70% animal protein (worms, slugs, isopods, soft-bodied insects), 30% mixed plant matter. Calcium dust at three feedings a week, multivitamin once a week. See our complete diet guide for the full version.
• Hibernation: none in year one. None. Keep them awake, warm, and feeding through their first winter, no matter what your local Eastern box turtle keepers tell you.
• Predators: rats, corvids, snakes, raccoons, dogs, cats, wandering toddlers. Hardware-cloth lid on any outdoor pen, full coverage indoor enclosure, never unsupervised on a patio.

One more thing about Florida bauri

If you are reading this because you found a hatchling Florida box turtle in the wild and you are thinking about raising it: please don’t. Florida law restricts possession of native chelonians, FWC enforces it, and the long-term science on hand-raised hatchlings released back into the wild is genuinely mixed — they often lack the spatial knowledge resident turtles use to survive their first winter and may import disease into the local population. The right call is to photograph it, note the GPS pin, leave it exactly where you found it, and email FWC if you are concerned about a specific animal’s safety. The keepers who do raise bauri well are working with captive-bred animals from legal sources.

The takeaway

Popeye and Pinto Bean were not unusual hatchlings. What was unusual was the keeper’s willingness to publish the boring infrastructure — the soak schedules, the gram‑by‑gram weights, the substrate readings — for thirteen months in a row. That data is what hatchling box turtle owners actually need. If you take care of the unglamorous parts (humidity, UVB, calcium, daily soaks, a gradient instead of a setpoint, no first‑winter hibernation), the cute parts take care of themselves.
