Not 100% Sure...

Hello, I have 2 Chocolate Indian Runners. I thought they were both male. I also have a female Aylesbury. Everyday for the last 3 days one of ducks have been laying eggs. I have no idea which one is doing it. Can my ducks cross breed? I am hoping you guys can help. Also my one runner has blue/green tint under its wing and the other has white. They are the same size and it doesn't look like their tails are curled any...

Pictures are not showing. Yes your ducks can breed and produce viable, fertile offspring. Both breeds are mallard derived.
