I don't think you can use a white leghorn for many crosses since they are Dominate White. All the chicks would be white.... with some leakage. But you would not see spots or chipmunk stripes with WL.
OK, I am now confused... I thought I got an answer to this..... To use a Blue Cuckoo Marans was best.... but I was told these would not breed true. If that is true, would they just be a sexlinked? I thought AUTOsexing breed true? How could I make these breed true? Or is it more trouble than...
Could you use a Cream Legbar roo x Cuckoo Marans hens and get autosexing? if so could you use a Blue Cuckoo Marans or would a Reg Cuckoo work best? I am thinking all the pullets if I used a blue would be harder to tell the color difference??????????
