Ringneck dove eggs

[Jimmytheringneck]

Hello, I am very confused about what is going on here. I have a pair of Ringneck doves yesterday I was happy to see two eggs in the nest. This morning I took a peek at the nest and there were two more eggs! Is this normal? should I be worried? The last clutch were duds.

Are you sure they are a pair? They could be two females.

Yes, I am positive, I've had the male for a while now and managed to get him a mate. I got her sexed just after getting her.
