Hello, I have a BBS pen with about 18 BBS Silkies. I am starting to figure out which ones are boys and which are girls. My question was when I confirm which are boys I wanted to keep only 1 rooster for the girls (should be roughly half of the 18). Which color do I choose? In other words which color rooster gives a better equally balanced ratio of Blue Black Splash chicks (not to give me like almost all blue, etc).
