I'm hoping some of you with more experience can give me a hand. I have 4 girls and in April my 2 yr old Wyandotte, Althea, started to have runny stools stuck to her vent. She also became lethargic over several days. I took her to the vet who found worms. I treated her and 2 of the others (I couldn't catch Eunice..) but Althea got progressively weaker and would not drink or eat. I brought into the basement, spoon fed her, but after 2 weeks she died. It was so so sad... The other girls seemed fine but then 2 weeks ago Eunice started to show the same symptoms. I wormed her (finally..) but there was no change so I added aureomycin to the water 3 days on, 3 days off, 3 days on, after talking to an old timer poultry farmer in town. He thought Eunice had coccidiosis. After 10 days I don't think she is any worse but she's really not much better. I just started adding ACV to their water yesterday plus gave them a yogurt/milk/layer pellet mix these 2 mornings. Honestly, I don't think anyone is eating that much but the other 2 girls seem pretty normal, though somber. I think they have reacted to Eunice's illness and hang around her a lot. The thing that really prompted me to seek your help today is I noticed Delores has some white on her feathers by the vent and now I'm in a real panic. Am I doing something wrong here? Should I continue with the antibiotics and if so, for how long? The girls spend their time between the coop and run, a good sized tractor, and then free range in the yard. They get a pretty balanced diet of organic layer pellets, kitchen scraps, and yard treats. I've read a lot of posts, but honestly, I am not sure what direction I should be taking. I'd love some help from you much more experienced folks...thanks..
