Hi! I'm sorry if this question has been asked and answered already but I have been looking for about an hour and can't find an answer. I have several (about 200) Chickens. I picked up one of my fav Buff Cochin hens yesterday and she was smelly, sort of like a dead carcass smell. I seem to remember that there is some sort of sickness, disease or parasite that is associated w/ this, but for the life of me, I cannot remember what it is. Can someone please HELP?! I have to nip this in the bud quickly, so none of the others get sick. She is acting normal, however. Thank you.
