I think my chickens are killing eachother

So we finally have our answer, it's (assumed to be) Avian Choryza.

Likely their immune systems were weakened by the changes in temperature and especially when staying outdoors in the relatively cold coop at night it likely weakened their immune systems significantly allowing the bacteria to kill them.

Gotta keep them indoors for a while and give them antibiotics, in the meantime we have to disinfect the entire outdoor area they have access to. Goose are seperated on another part of the property, thankfully it generally doesn't affect geese and they're mostly just carriers, but we'll keep theblems.m seperate for at least a while to avoid problems.

The 2 ill chickens are still alive as well and both drinking their water with antibiotics. We'll have to see how it plays out.

Update, the ill chickens are back to normal, one of the geese got ill but she also recovered.

Question is what do we do with them now? From what I've read online sick chickens become carriers for life, does this mean we can never return them to the flock?

Considering they were with the flock when they got sick, I would assume that every bird on the property has already been exposed. So I would put them back together, but beware of bringing in new birds. And of course be ready to treat any others that do get sick.
