I picked up one of my juvie sultans today to look him over, make sure the flock is well, etc. It's pretty easy to see mites if they get them just because they are white chickens with pink flesh. Head was mite free and no sign of other bugs there. Flipped him over to check his vent and right at the base of his tail feathers there was a bunch of bugs congregated. They are about the size of a large flea but pinky flesh colored(nearly the exact color of the chickens skin tone) and ran like crazy When they seen they had been spotted. Are they lice of some sort?
