I saw two of my button quails, Tac and Chickapee, mating. Tac grabbed onto her head during mating. Could this be the reason why Chickaoee has lost feathers on her head? I originally thought it was from pecking, but the only pecking I've seen was from this. Also, how do I know if my button quail is "pregnant"? Will she not lay eggs because there are 2 males in the same cage?
