Since the coop was broken into and Cheeps lost his family he's been scared to move, and just hunches into himself. I thought he was coming out of it but this morning when I opened the door he staggered and fell. I got a little water down him but the only thing I've gotten him to eat is mashed pears. What can I give him to get his strength up? I haven't found obvious injuries but he could have internal. It will be one week tomorrow night since the break in. What can do I for him?
