we have three roosters that we seperated from the rest of the flock cause there were too many roosters in with the hens. We ordered more pullets so they would have thier own females and we were making a seperate room for them cause they are still pretty little. My sister went and picked up one of the roosters and remarked that they seemed to be loosing feathers, then when she stuck them down there were little yellowish tan bugs on her jacket. I put some mite stuff on them but im not sure they are mites. Today i went and examined them more closely cause yesterday we were too busy to do so and they have a gray mold looking stuff at the base of thier feathers mainly thier tail feathers and vent area. Does anyone know wether that is caused by the bugs we saw or is it a seperate thing? Also does anyone know if they are mites?
