I am interested if anyone has tried crossing the Cayuga on a breed that lays a good blue egg- I think a black runner Cayuga cross would lay beautiful eggs and be a good forager. If anyone has done this cross what do the eggs looks like?
Cayugas can lay cream or green eggs. The black "bloom" disappears as the laying cycle progresses. In order for them to lay green or blue eggs, they must have 2 copies of the gene. So crossing a white egg laying cayuga with a green egg laying runner won't give you green egg layers unless the cayuga carries the gene. It doesn't mean the eggs the offspring lay will me a mix of the colors like you are suggesting
