Hello, I'm not sure where to post this question. I have a female Pekin duck and two (one white and one gray) male call ducks. If I were to try to hatch her eggs is there any way of telling what size the babies would be. The reason I'm asking is because if they are smaller than pekin would they be able to hatch. I don't know if they'd be able to peck their way out of the bigger egg. Has anyone ever crossed a call duck with a pekin and were results successful? Thank you for your help.
