We recently got our first chickens. They are now just over a week old and one has been quite sick. She is Failing to thrive, lethargic, droopy wings and bloody poop, eyes closed etc. I started them on a sulpha based treatment on friday night (it was all we could get at the last minute) and Cocci-vet on saturday. Yesterday peep peep seemed to have pepped up considerably but today seems to be worse and is sneezing much more. she is making the saddest little cheaping noises . I have been supplementing her with a high protein baby bird starter. Is there anything else i can do? is she likely to survive or am i delaying the inevitable?
