I made this cross just for fun: dark brahma rooster and giant black cochin hen and the chick was a rooster, he is now 2 years old he looks like a giant cochin rooster but taller, has a large pea comb and has the coloring of a dark brahma rooster.His father died this spring and i want to use him as my maint rooster on his father's girlfriends(dark brahma hens). How will the chicks look(they will be 75% dark brahma and 15% black giant cochin)?
