I have three supposingly Americuanas, but I think they are Easter eggers. However one of them is being lethargic since yesterday. It is about 7 to 8 month old and not laying yet. The crop seems completely empty (at about 3pm). I gave some of their favorite snacks earlier, some dried worms, with some yoghurt and she ate some, also drank some water this morning. I don't know if she is pooping or not, but checked the coop and none of the poop looks unusual. Her comb is not fully developed yet, but color looks red as always, eyes are open, beak closed, doesn't seem to have trouble breathing. She looks a bit hunched in itself, the tail feathers are down. Once in a while she twitches a little. I was browsing the forum for the last hour. I am not sure what to do. Just start her on antibiotics? Give more yoghurt, and if so how much? Could she have worms, and if so, how would i find out? Any advise is greatly appreciated.
