I have 12++ fertile duck hatching eggs. They are mixes. Cayuga/white crested. They are adorable. I have hatched out 2 crested Cayuga's in my last hatch. Hatched out 10 out of 11 two days ago. Fertility is excellent. Many chocolate brown babies have come out of this combo. I have 14 eggs so far, will send whatever is laid in the next couple days. 2 females to 1 male.
