My chickens had mite last year. while I was holding my silkie I noticed egg masses in his beard and ear and vent area. I didnt find any mites. Are the eggs mass still there from when they had them a while ago ? I checked all my birds I only found egg masses on the silkies and not the other birds( they were separated when they had mites the first time). I dusted with left over sevin 5% dust just incase. My male silkie is really skinny and bony . . .If he had mite would they do that ? They are 8 months old he doesnt mate yet, he started crowing . . .but stopped . . . is he this way if he had mites ??
