Thank you. As far as I can tell I have a pullet and cockerel of each type,and the 3 types being Silver Sebright, Golden Sebright,and Butterscotch booted bantam. My LF I am getting are Dominique,Buckeye,and Rhode Island Red's. They will all be sharing a 8x12 coop with a 16x24 fenced in run.
Your video would not play it said PRIVATE, I can't see what they look like. I think sebrights are hard to sex because the males have "henny" feathers. You could put "Sebright thread," in the search box and see if one comes up. The folks that breed them would be able to offer you the best advice.
