Yes you can breed. But the daughter chick is blackshoulder split to midnight and her father is only IBBS. The chicks that you will get from this cross are 1) IBBS, and 2) IBBS split to midnight.. Since your goal is to produce a midnightBS male, may be a female, It has to be son to mother. You know that charcoal hens do not lay eggs, even if they do, they wont be fertile, at least what I learnt from this forum. To get charcoal pied chicks (male and female), 1) we need two charcoal or split to charcoal parents. 2)One parent must carry a white gene, which means , A charcoal split white parent. 3) the other parent like we said must be a charcoal and also must carry a pied gene, Since the pure charcoal hen do not lay, she must be a split to other colors, example IB split charcoal. Like we said , this particular hen must also carry a white gene if the male is carrying a pied gene and vice versa..... What I do not know is that a charcoal hen split to any pattern color, white,pied,BS,w/e etc. can lay fertile eggs ????. Your 2 yr old IB split charcoal hen can be used as one parent, ony if she is either SPLIT TO WHITE OR SPLIT TO PIED. otherwise you will not get pied charcoal male chick from this hen. The pied split charcoal male is perfect as one parent , since this male carrys one white gene and one pied gene.
