Sick chickens

[Chickenarmy4717]

I got 7 chickens. I had 4 from one breeder and I got 3 more chickens from another but one of the smaller chickens were sick when we got them. She's slow tired and always has a runny nose. We had them all together and we through that it would be fine since the last said the hen had been treated for it and now all my chickens are sick we have tried antibiotics and talked to a vet but so far they have just gotten more sick my australorpes have gotten the worst of it there faces are swollen and all there faces have gone pale some of them are a tad bit better but there all sick. What do I do

Hello! Welcome to BYC! Sorry you have sick birds! Go to the forum list page and start a thread in the topic: Emergencies / Diseases/ Injuries & Cures giving a description of the sickness symptoms. One rule to think about is when adding more birds to an existing flock any new birds should be kept in quarantine away from the existing flock and watched for signs of illness for at least a couple of weeks before integration. I would not have purchased any sick birds even if they were given meds. A responsible seller would not have sold them to you! Good luck and I hope they get well soon!

Welcome to BYC. It sounds like it may be mycoplasma. Its not curable but it can be managed. Here is a screenshot from google that may help you.
I've read that an estimated 85% of flocks in the US have it. I do not know if that is accurate.
