Our goose and gander are about 9 months old. Our goose has not started laying eggs yet, but is definitely going through puberty. Whenever my boyfriend gets near her she crouches down as if she wants him to mate with her. Today, we caught her trying to sit on the ducks' eggs. However, our gander has shown no interest in mating with her. He has, on the other hand, attempted to mate with our most promiscuous duck several times. So what gives? Are they just too young? Our goose is beautiful so that's definitely not the problem.
