Description: The Florida chicken turtle (D. r. chrysea) has the most distinctively patterned carapace of all the chicken turtles, featuring bold, broad yellow-orange reticulation. The shell is cuneiform (wedge-shaped), especially so in males and juvenile turtles, and measures up to 6.5 inches for males and 9.8 inches for females. The subspecies name chrysea is taken from the Latin for "golden one" due to the bright yellow or orange color of its plastron.

Habitat: Chicken turtles are semiaquatic, equally comfortable in wetland habitats and on land. All three subspecies have similar preferences; they like quiet, still or slow-moving bodies of water such as shallow ponds, oxbow lakes, drainage ditches, borrow pits, marshes, swales, cypress swamps, and Carolina bays. Generally, the chicken turtle prefers water with a maximum depth of around 2.3 feet, but it is known to inhabit ponds up to 6.6 feet deep. It rarely inhabits moving water such as streams or rivers, but may sometimes colonize quieter rivulets or pools in the riparian zone. Furthermore, it strongly favors fresh water, avoiding brackish water wherever possible.

The chicken turtle thrives in bodies of water with dense aquatic vegetation and a soft, muddy substrate. Often these are ephemeral or temporary wetlands that readily dry out during the summer or in periods of drought. Such habitats tend to be free both of fish, which would provide competition for food, and potential predators such as alligators. When drying occurs, chicken turtles will migrate to the land and burrow into the soil or hide under foliage to avoid dry weather. Although they are well adapted to living terrestrially, they rarely abandon their original habitat even during extended dry spells, and will relocate to the water once it returns.

Although the chicken turtle does not generally inhabit islands, isolated groups are also known in the Outer Banks chain of barrier islands off North Carolina. These maritime forest habitats are prone to drying out easily in the summer and can be affected by storms and sea spray, but research into one of these groups found no meaningful differences in longevity, growth rate or sex ratio between members of this population and their mainland counterparts.

Range: As its name suggests, the Florida chicken turtle is native to Florida and is only found within the state. It is relatively widespread throughout the central and southern portions of the state, although it is absent from the Florida Keys.

Diet: Like many emydids, chicken turtles are almost completely carnivorous during the first year of their lives. However, they are unusual in preferring a carnivorous diet into adulthood. It has been suggested that this explains the smaller local populations of D. reticularia compared to other related turtles due to competition with fish for food, especially insects. In the wild they are known to prey on crayfish, invertebrates, tadpoles, vegetation and carrion, including dead fish and other animals.

Reproduction: The mating season of the chicken turtle can be estimated by the times of year in which male testicular volume is greatest, indicating maximum sperm production. This period varies by location; in Florida, the testes are largest during the hottest months of summer, while in South Carolina and the slightly cooler climate of Missouri this occurs in the late spring and early summer months, roughly May through July. In Texas, courtship may take place in the early spring (February to April) or fall (September to November). The chicken turtle's mating ritual is initiated by the male, who swims at an angle towards the female turtle until he is facing her head-on. He then attracts the female's attention by making short, rapid swimming motions, gazing at her and vibrating his outstretched foreclaws against her face and neck. Only if the female is receptive does copulation occur. There is no evidence of forced insemination as sometimes seen in other related turtles. Chicken turtle mating takes place in shallow waters, and reproduction can be disrupted by prolonged periods of dry weather.

Like mating, the timing of the nesting season depends on latitude. For example, in Florida nesting takes place continuously between mid-September and early March, with the possibility of an interruption if the winter weather is particularly cold. Further north, nesting may begin earlier in the year (around the end of August) but is always paused during the coldest months before resuming in the spring. In South Carolina and Arkansas, nesting and egg laying may recommence in February, while in Virginia, in the northernmost reaches of the chicken turtle's range, it may not start again until March. This pattern of nesting in winter and hatching in spring is highly unusual; the chicken turtle is one of the only native North American turtles to nest at this time of year. Several reasons have been suggested for why this behavior developed. One hypothesis is that it allows the hatchlings to emerge in the spring when there is a good supply of food available and less competition from hatchlings of other turtle species that appear later in the year. Furthermore, predators of turtle eggs may be less likely to hunt for them in the spring when there are generally fewer to be found. Atypically among North American turtles, the female chicken turtle can retain fertilized, calcified eggs in her oviducts for several months after copulation, especially over the winter; these eggs will be laid in the spring once the nesting season resumes.

The female nests on land, often in loose soil, but sometimes in heavier ground. She digs out a cylindrical cavity with a depth of around 4 inches and a diameter at the opening of approximately 3 inches. Nests are usually built close to the water, although females are known to wander up to 306 yards in search of suitable sites. Once the nest is ready, the female deposits a clutch of between one and nineteen eggs. The eggs are white with a leathery or parchment-like shell, and elliptical in shape, measuring approximately 1.10 to 1.61 inches by 0.67 to 0.98 inches. Egg mass varies considerably; a review of eight studies found reported averages between 0.3 ounces and 0.4 ounces. The mass appears to be positively correlated with female body size and eggs laid in fall are significantly heavier than those laid in spring. Several minutes after laying, the female will fill in her nest, sweeping the dirt over the eggs with her hind legs until they are covered. Chicken turtles commonly lay two clutches of eggs per year,although in the uninterrupted nesting season of Florida, females have been known to produce as many as four.

Status: The chicken turtle population as a whole is currently considered secure and is thought to consist of at least 100,000 adults. Local populations are often small but stable, however the species is designated by NatureServe as S1 (critically imperiled) in Virginia and Missouri and S2 (imperiled) in Arkansas, Louisiana, North Carolina and Oklahoma. The chicken turtle does not appear on the IUCN's Red List of Threatened Species, although the Tortoise and Freshwater Turtle Specialist Group's own provisional list considers it Near Threatened. At the state level, the chicken turtle is protected by various local laws. In Virginia, where only around 30 adults are thought to remain, it has been listed as "vulnerable" since 1987. It is also considered at risk by the Alabama Natural Heritage Program; local regulations state that only two turtles may be kept and these must be for personal use (e.g. as pets). Along with other native reptiles, removal of chicken turtles from their natural habitat is regulated in several states throughout its range including Texas, Georgia and North Carolina. The chicken turtle is subject to a ban on commercial taking in Arkansas, where it is "extremely rare". In Missouri, where until 1995 no sightings had been recorded for at least 33 years, it is listed as an endangered species, making hunting illegal.
