I had my peacock and peahen for less than a year. The former owners said the peahen had laid a few eggs 2 years ago. I adopted them this past Fall. I built a large enclosure, approximately 10' x 10' x 25', and placed them inside. For the past several weeks, Azul, my peacock, has been displaying his feathers and making his mating call. I've actually seen them mate three times. But, there are no eggs. Any idea what's going on?
