I have had chickens for a few years. Never had any health problems. I purchased two new pullets to keep my lonely hen company (they aren't in the same coop yet) . I purchased them on Saturday, did not handle them that day to give them some space. Upon handling the EE I didn't notice anything but a pale comb but the buff had lice crawling on her & I. All I had was DE which I use in the coop. I dusted her , then on Tuesday used poultry protector on her & her friend. After their color came back a bit but the buff has foamy poop . Not all the time but a couple times a day. The women I bought her from didn't know if they had been vaccinated so they are in medicated feed (was planning on switching to grower feed soon) they are eating & drinking a lot but I'm worried the buff may not be well. Should I treat her with Corid or give her some time.....:/
