I am not sure what to do at this point so any advise would be great. Ok the smallest laying hen has been hanging out in the coop not all the time but a little more than usual lately. The fan is in there so I figure she is hot. I picked her up the night before last to check her over just in case. I did not see any mites but I went ahead and dusted her because we have seen a few on some of the others. I have been trying to keep that issue down using de and 7 dust. Ok so we found her dead on her nest this morning. She had half her body though pulled up under the wire we have surrounding our inner walls. Not sure if she was in so much pain she crawled up into there herself or if something maybe dragged her. BUT there are no marks. I dont think I feel an egg but she was stiff and its hard to tell. Then I looked at another of the hens and her foot is HUGE. Its swollen and hot. I don't see anything especially wrong with it. No holes or cuts that I can tell. No bleeding. Just huge and swollen. What could I be looking at and how do I treat it. Is there any link to the other hen dying maybe? These are red production birds. I was told they were a year old but I have some very serious doubts about that. These were in pretty rough shape when I felt sorry for them. They were getting to be somewhat pretty again. They get layer feed, they steal the high protein game crumbles when they can, they get anything they can forage while ranging, they also get veggies tossed to them from the garden, oyster shells, crushed egg shells, scrambled eggs, and a little bit of fruit. Right now mostly blueberries.
