This is a slider that was found crawling in someone’s backyard. They know we have tortoises, so they asked if we wanted to help it. Unfortunately I have zero experience w/ water turtles, generally. There isn’t a strong smell, but my son says it’s there. I see pitting and the seems to be sloughing off in places. The skin also looks like it has sloughed off in places, but there is no redness or wounds. So basically… I have ZERO clue how to care for this seemingly sick turtle. Your thoughts would be appreciated.
