[Hello, Thank you everyone for your help with my fox-attacked chicken. She is now back to 100% health! I picked up some chicks 5 days ago of varying ages (2 wk old buff Cochin, a pair of 5 wk old legbars, and a 3 month old speckled Sussex) to build my flock back up. I didn't quarantine (dumb, but I apparently like to learn the hard way). One of the legbars has had an on-again, off-again crusted shut eye since he came home, but seems normal. Yesterday, however, the happy, running-around, chirpy buff Cochin (named Pants) got lethargic, and within a few hours was sneezing and having trouble breathing. She currently keeps both eyes shut, occasionally needs to breathe with her neck stretched out and beak wide open, and this morning I found bloody stool next to her (which was exactly where I'd put her last night at bed time). I have her quarantined from the rest of them now. I gave her some water with ACV by dropper on her beak. Her crop is empty but she won't eat. I'm thinking this could be cocci? Does it also cause respiratory issues? I'm doing some reading in my chicken health book, but would appreciate some first-hand knowledge of how to care for her and the rest of my flock. It seems it's been nothing but chicken problems for me this last month! Thanks again in advance!! I hope someday to have enough knowledge to share with others like me!
