Yesterday we brought him in from the coop where we found him laying on his side the same way he is doing in this picture. We thought he was actually dead. I brought him inside and put him inside a dog crate with food and water and he was standing just fine as well as eating and drinking. When he does fall down like this.. he just sits there and doesn't try to get up. If you pick him up and put him on his feet.. he will walk around normally. Any ideas?
