Hi,,,, we have just got a few chickens, with more to come. My question is.... We also have homing pigeons. Pigeons always lay 2 eggs, and one will hatch a hen and one a cock bird. (The hen will have the markings of the father, and the cock bird have the markings of the mother). Anyways, do chickens have any sort of balance or predictability like this? Thanks,,,!
