I got an americauna week old chick 4 days ago with a group of 6 other chicks. one died the same day we brought it home from unknown causes. this one has been fine until today. i noticed it sleeping, alot. (but sleeping standing, so at first she looks fine) she is really slow. when i move her, like on her side, she does nothing to try to get back up, just lays there. she has clean water and chick feed, and seems to be breathing fine as far as i can tell. a heat light as well, so they have heat when they get too cold and have room to move away to cool down incase they get warm. i have no idea why she is like this. please help, i don't want to lose another chick!
