At hatch I cull right away for 6th toes, 4 toers, if I can see single combs starting, skin color, double nails, feathering to mid toe, splay legged ones, etc. At about 4-6 months I cull for color, bumpy combs, wings, etc. On colors I have pretty well started in, I cull hard for everything and only hold back the best. In project colors, you have to be a lil more lenient til you build up your breeding stock. In cockerels, I keep best 1-2 of each variety back for breeding, 1-2 more for showing and sell rest of good ones to other breeders. Culls go to pet homes if they can and rest go to Asian friends for their dinner.
Thank you for the details! I appreciate it. It takes so much time with silkies! All the ones I hatched to start with in spring are 4-5 months old and really just starting to develop into their male vs female figures and combs are just becoming apparent. It's a long journey with silkies!
