My 14 week old Ancona has been sitting around all week, but it has been raining a lot so I didn't really think that much of it. Today she couldn't walk so I examined her legs and they are swollen and lumpy!! I will try to get a picture, but what is it! They are not swollen like scaly leg mites, the skin in swollen. I am giving her vitamins and honey right now, I don't know what else to do. Thank you! ETA:I opened the coop and she was dead. Can it infect and kill my other chickens? please I don't want to loss them! ETA2: Okay I am officially a bad chicken mother. I just went to lock up the coop and counted the chickens and I panicked when I couldn't find my SLW, so I did a head count, and I still have 5 Anconas!! my SLW died this morning and I assumed it was the sick Ancona! The sick Ancona is walking around better, and is looking so much better it took me all day to realize it is the same chicken!!
