Hello, I am relatively new to breeding poultry. I wanted to begin breeding chickens with the end goal being showing my chickens. I have read quite a bit about selection for breeding and most of it concerns choosing which two chickens to breed together. I would be interested in peoples opinions on how they choose chicks to keep as potential breeders. Like lets say you hatched out 100 chicks in the spring. Obviously for most people you could not raise all 100 chicks to adulthood due to space concerns. The question is then how do you select which chicks to keep and which to sell. Obviously some might have clearly visible flaws like a crooked toe or beak etc., but which stages of development are most critical for determining which chicks will grow to be beautiful birds. For example at 6 weeks should you begin to look at comb development or 8 weeks for proper feather development or conformation to type. I was hoping someone could provide some guidance for how I might most effectively cull and sell chicks which will likely show less promise. Thanks..
