My CAG fell yesterday with his cage. He was probably on the cage as when we arrived we found him hidden under a chair. He hasn't made a noise since then. He is all fluffed up and I don't think he drank water. He didn't even touch his seeds , but I gave him cherries and he kind of ate them. He doesn't get out of his cage unless we put a cherry on the cage(he usually sat all day long on top of his cage , playing ). I don't really know what to do, he looks like a sick bird, staying inside the cage with his eyes half opened half closed.The worst part is that we're leaving tomorrow( we'll return in 2 weeks ) and we will let him with our uncle.What can I do?
