Sorry I never saw your posts to reply. Somehow I wasn't getting notified. Anyhow, I will take all of this into consideration when thinning & culling. Thank you everyone for the info.If you're breeding to sell hatching eggs I can see where POL at 11 months would be a problem....unfortunately all the people before you breeding these new varieties just to sell eggs/birds is what created the problem in the first place. If you plan to be a serious breeder and want to improve your line you can fix the problem in time.
As your chicks grow take note of the pullets that start laying first and give them special consideration as breeders. Cull for type and vigor first then color. Same with the cockerels...mark the ones that feather earliest and mature fastest. If you make utility a priority you'll end up with a line of beautiful birds that are what they were meant to be...a meat bird that matures in a reasonable amount of time and lays an acceptable amount of eggs.
Good luck!
