Hi. I am new to the site. Still Learning how to care for our new Chickens. Here is a little back story. We bought two chickens from the Flea market about 3 months ago. After the first Month, one was sick with matted eyes and lethargic. Then Died. The other chicken never got sick. About two weeks after we brought in 4 hens and a Rooster, Everyone seemed fine. It's been a bout a week now and Our Rooster is really sick. Matted eyes, drainage, runny poop and not active at all. Another one of the Hens is sick also, Still drinks and eats but sick. I have been researching some things and it seems to me that they fit into the MG respitory illness. Not sure what to do. What if you do not want to kill them? Will we ever be able to have more? Trying to determine what we need to do. Thank You for any Advice.
