Hi I recently had an outbreak of what I think to be cocci and sour crop. I don’t know what they ate that caused this but we’ve already lost two of the five chickens in our outdoor flock (we have one house chicken she is upstairs sick chickens are downstairs). I have one bird that appears to have both cocci and sour crop. One that appears fine and one that just has cocci. My question is how do I treat the one with both sour crop and cocci? My house is completely full of chickens and I’m absolutely terrified. We just recently got new chicks too (so that our house chicken would have a less aggressive flock to potentially be with and I don’t know what to do. Should I give the one that isn’t sickens the house chicken a preventative dose of corrid? And what about the chicks?
