Hi there! I have had chickens for a couple of years now but I am very new to ducks. About a month ago my husband called to tell me that he was bringing home two "very ugly baby geese". . . . turns out they are Muscovy ducks! There is a drake and a female, and the guy that gave them to DH said that they were 12 weeks old, (but he also said that they were geese, so I don't know how reliable that is!). We have had them for about four weeks now and they are very friendly. I didn't think the female would be laying yet because she seems pretty small still, but I found a nest in the coop with three eggs in it today, and I found what I suspected to be a duck egg on the floor of the coop four days ago, (and my chickens NEVER lay outside of their nesting boxes). She is the same size as my barred rock hens, and the drake is about twice as large as her. How can I tell how old they are, and how likely is it that the eggs are fertilized? We didn't want baby ducks, but I don't want to put the drake by himself because I don't want hime to be lonely. Thanks.
