Hey, I bought a pair of silkies from someone on facebook and after coming home and inspecting them I noticed one chick had a wound on its back neck and quite a few yellowish tiny bugs within its feathers and the other chick also had a couple of the yellowish bugs. Now I’m worried to introduce them to my existing flock should I give them away or what can I do, as of now I’m quarantining them. I’ve attached an image of the wound.
