I understand your comment. But when you start with only 6 hens and two cocks - that combination didn't produce eggs needed .
That is even more critical when two of six go broody LOL
Thus the laying flock . That however will change when we get to a point all hens are breed forward type.
I sure had more fun hatching this year with more females in the breeding pen. I SHOULD make more careful choices of females next breeding season, but I don't enjoy the stress that causes when organizing clutches. I'm not sure I'll ever be one of those "single mating" breeders. Unless we get to the point where we're making tiny tweaks or trying to run experiments. That would require tweaking our set up a lot.
I got chastised by a local breeder a week or so ago for indulging in the hatchery layers & mutts. But then when I explained the math with the egg-to-customer ratio, I got temporary permission to carry on with the hatchery birds until the Delaware numbers are up. The layers are paying for the feed for the chicks at the moment.

As a grown woman who doesn't feel I need any scolding, I didn't admit that I also think we have too many hatchery birds around here.

I THINK we worked out the major kinks for culling last winter/spring.
