Bert, Lacy seemed to die of an egg-related issue. We found loose yolk in her abdominal cavity. All her organs were the picture of health (yes, we opened her up and checked their condition since she looked like she just fell asleep and died).
After Hawkeye died, and Zane was trying to make his place in the flock, he was being harrassed and pushed off one of the high roost bars by the older hens. He was frantically flapping his wings when he missed the next one up and just couldn't make it, so he fell to the floor. There were lots of shavings, hence alot of padding, but he did lean against the wall for a few seconds like it really hurt. I was standing in the coop and couldn't get to him in time to catch him. He must have twisted his back. His foot was really swollen, but that has since gone down. When he stands, one shoulder is now higher than the other, just like my DH when his own back is out, so I think he's in lots of pain. And his wings sort of hang a little. One postive note, or at least I feel it's positive, is that he will on occasion, stand up and slowly flap his wings. Maybe it will just take time, but I am worried that he won't eat enough to keep up his bodily functions and general health till he feels better. The garlic is just for the same thing people eat it for, his immune system. He seems to like it because he eats the tops of the garlic growing in the yard. Not all chickens like it, though.
