Hi everyone! I have a question im hoping you can help with. Below is one of my chickens first two picturea last week, third one today. Can anyone help me? I treated with elector psp last week and sprayed the run, changed the bedding and sprayed the coop. A friend told me it was possibly mites. I treated all 11 girls- I didnt see anyone with any mites, but treated anyways. This girl still has thins bald spot and today one of her tailfeathers is bloody. Doninre treat her, is she getting picked on? She laid yesterday and is eating and drinking
