I believe if you boil water that will take the chemicals out? Also you can fill a big pot with water and let it sit for 24 hours and that will take care of the chemicals……
Outdoors. The flooding we had must’ve brought him up from somewhere maybe? Or a bird dropped him. I wasn’t sure what to do with him…there’s not even a pond within a mile of the place I found him, in the middle of a parking lot. It’s tiny
I’d really suggest releasing it back near where you found it, or turning it over to a wildlife rescue. Wild turtles do not do well in captivity. Depending on where you’re located, it may not even be legal for you to keep it.
Edited to add: This is assuming RES are native to your area. If not, I’d still suggest turning it over to someone with more experience, as wild caught animals have a higher risk of parasites, disease, and being hard to acclimate to captivity.
Realistically you should put it back. Find a body of water nearby where it was found and release it there, or contact a wildlife facility. Nature needs not be messed with.
Im a wildlife technician and we are always relocating everything (because I cant keep them all )
If you do release it, great. Maybe find a local pond or retention pond that has other turtles in it.
If you do decide to keep it, remember lighting is everything. Research UVB lighting approved for RES and also they do require fairly large aquariums. Adult females should be kept in large outdoor ponds (like those big black tubs you see for koi).
Being wild a fecal check for parasites by a vet should be done asap along with any other tests a vet recommends.
Releasing it is always best imo. This little turtle could easily cost you hundreds if not thousands to properly care for to adulthood, so keep that in mind.
