This is so interesting I have one paint chick growing out now not sure of sex yet when it was very young I thought roo based on behavior now it is looking kind of like a pullet the comb isn't growing as quickly as some of it's hatch mates. I am hoping for a pullet so I'm sure it will be a roo Lol I will try breeding it to different colors to see what I get first will be to my black. I would love to get a few with the red frosting they are beautiful.
