Hi my ducks have been laying eggs like crazy this past month & one I cracked was actually "fertile" as it had a tiny duck smaller then a dime in the egg. So I placed a box down to try & help the ducks. I have never had ducks breed. I have chickens, chicken eggs must stay clean. I think it is the same for ducks but my ducks eggs stay dirty. Are the ducks eggs the same as the chicken eggs? Can I do something to keep the eggs clean? What is the best method for allowing ducks to hatch their eggs?
