Hey, I have a chicken who is about 4 months old and I left for two weeks to go hang out with some friends. I came back home, his feet were crooked, very large compared to his body and he couldn't walk very well at all and would trip a lot. I thought maybe somebody had stepped on him, or like he fell off my bed? But just as of two days ago, I went to his cage and I thought he was asleep, so I picked him up very gently and then set him on the floor outside his cage. He wouldn't move. He laid there, limp. I don't know what happened! He wont eat at all. He cant move his head, I have to lift his head up and put it into the water dish for him to drink at all. He tries to rearrange himself sometimes and cries out in pain whenever he does so. He wont eat no matter what I offer him. What could have happened? I'm so scared he'll just die on me soon. EDIT: he also has a very bad smell about him.
