So I have a bearded roo, one bearded hen and 2 non bearded pullets, all hatchery bbs silkies. I don't have things set up to know which eggs are whose, but out of 10 eggs, 9 hatched Jan. 1, and I don't think that there is a bearded one in the lot. Is it chance, or will I get bearded from the bearded roo and bearded hen?
