Our hens are 3 months old now and were doing just fine yesterday. But this morning I went out to feed them and Minerva Louise was just sleeping on her perch while the others were getting down to business with their breakfast. She is not wanting to eat, only took a peck or two at her food, and just sleeps, sleeps, sleeps. Her tail is down and she obviously is sick. The one dropping I saw was runny, clear with a bit of black/grey in it. Not much white substance. I have NO idea what's wrong. The feed store has something to treat coccidosis and a variety of other ailments, as well as worming liquid -- I don't think it's worms. I called an avian vet and they want $90 to examine her!!! I just can't justify that. SO anyone with some experience here feel free to tell me what I should do.
