I bought two male buttons a while ago and then I bought two more a bit later! The two newer ones are white so I never knew which one was male and female! Now I'm certain I have 3 males and 1 female! I know this is a horrible ratio. I divided the aviary floor with a plastic mesh so now I have one male with the female and they have started mating! But the thing is the female has never laid any eggs as far as I know! Could mice have taken them because they sometimes get in at night but I'm busy fixing the mesh so the mice cant get in any more! Why do they mate if the female doesn't lay eggs? She is old enough and when he tries to mate she lays down on the ground and doesn't resist or anything! Winter is just over now and spring is slowly starting.... could this be the cause o no eggs?
