About 4 weeks ago they had mites which we dealt with. They ar both pulling feathers out around their necks and under their chests. Have checked for mites and can't see any but did them again just incase, and have sprayed their feathers with anti peck stuff too but they are still doing it. Seem very happy and are still laying fine. What is causing it?Is theit mites that I cant see?Are they bored? help please!
