I was getting a little worried as yesterday was day 35 for my Muscovy hen and nothing. So, this morning I decided I better check some of the eggs and see. I was worried maybe they were all duds. I pulled one out from under her (she graciously just peeped at me instead of attacking my hand) and the first one looked like a dud. I'm not great at candling so I stuck it back under her just in case. Pulled out egg #2 and there was a hole and it looked like it was about half way done with the zip!! So I put that one back under and left her be. So babies are on the way again.
