Try putting voporub on the bites, it should helpI'm so miserable!! I have chigger bites on my ankles the backs of my legs and a few on my back. I've done the finger nail polish, Benadryl, cortisone lotions ect.
discovered a trick with your little roo, separate him from any females in sight, that has settled him down quite a bit, and he is getting evening handling - his cage is in the livingroom, so he is getting re-socailized too
