Good point. Rare breeds are a challenge. We raise only for our own needs here, so I just want to maintain a healthy & consistent flock. With a small flock though, would it not be feasible to just hatch eggs you know, came from the best of both bloodlines of hens? I know I have more challenges ahead. I can't breed brother to sister in future, so I'm hoping that I can grow out an old line/new line cross cockerel this spring, to cover the oldest hens next year. I'm trying to get distance between generations & using the new bloodline to get some much needed vigor back in my flock. I can only hatch out 25-30 chicks a season. Yeah, a pretty tall order! Hard to get much improvement at that rate, but I know it's a long term commitment. I'm still waffling on whether I should hatch chicks from father over daughters. Maybe I should just hatch chicks from my only rooster over the 2 new line hens I have now?
I could hatch every week if necessary to get the numbers I need.
