I have two broody muscovy ducks right now. And I really don't need any more muscovies. My other ducks are khakis but I have a pekin drake and a khaki drake in with them. I don't really want mixed breed ducklings. So I ordered eggs. The eggs had a long journey and the air cells were all detached but don't look damaged. They have been sitting in an egg carton for over 48 hours and the air cells still have not reattached. What should I do? Should I give the ducks a few possibly mixed breed eggs and hatch the shipped ones in the incubator? Should I wait a little longer?
