I've been having nothing but troubles with my chickens since a fox got 9 of them in the spring. I got some replacements which had lice, respiratory infection, worms etc. They were dewormed, treated for lice, and given a round of antibiotics. Well, most of them are much older than the woman that sold them to me said they were so they, and 9 other older hens are going to the butcher tomorrow. One of them decided to develop a bit of a wheeze yesterday. Is it still ok to have her processed/eaten? I haven't given any antibiotics.
