I had a pair of quails who I bought together when they were two months old. The female never laid eggs and the male tried to mate with her, but was always unsuccessful. Two months later, the male suddenly died (I'm not sure how). I bought another male and female (who was already laying. She laid an egg on the way home) who were about the same age as my other female. The male was immediately mating with both females. The next day, both females laid, and they both laid every day for the next few months (until one went broody).
Is the male related to the females? Did they grow up together? Sometimes, when they grew up together, the don't form a mate bond, but rather still see each other as siblings (this especially happens with king quails though). This could be nothing to do with it.
Also, sometimes the males aren't quite as hormone crazy.
He is a beautiful male by the way
