I do cull carefully at hatch, usually selling the extras to backyard layer flocks and etc. Each mating will have a different priority, but overall, I rely heavily on my instincts. I have some I can cull right away, others I will wait a few weeks, because I want to be able to know for sure what will and won't work.Haha.... OK on the other thread since it is a black copper.
Another Question.... do you cull at hatch for coloration? I get about 1/2 with the better white markings... not as good as the one I was asking about but normal like your pink. I think Vicki does I am sure Don does. I would like to really improve quickly and if that would be a HUGE help I can do that.
