I bought a trio 2 weeks ago, a rooster and 2 hens, well I notice one hen didn't act right one day last week like she was weak, she wobble backwards, I thought it was odd, but if I knew what I did now I would have done something! We found her dead Sunday and now the rooster is sick! He can hardly grow and having a hard time breathing and combs bleeding, I put him and the other hen in a pen by themselves, but I think its too late as I have a skilie that's now sick! I let the man know that he sold me sick chickens he said he didn't know they was sick and that it could be the weather........... Does anyone now what they have? I have already started antibiotics on the 3 sick ones what esle can I do? Thanks any help will be greatly helpful!
