I am putting my best spring cockerel over all of my old hens in a separate pen. The cockerel will be the son of one of them, and new to the rest. I will see what comes out of that pen and decide from there. I am culling the #3 (last years) cock and putting the #1 cock over the best spring pullets. I will also cull two of the breeder hens that didn't produce as good of chicks this year. I keep the best cock of each line, and a backup cock from each line as well - total - 4 roosters.
That's my plan and I'm sticking to it.
I'm trying to make a plan ... like that matters much as things happen to mess up my best plans.
I'm only growing out my second season of chicks, and am not sure I'll have better birds this year than I had last year. I'm super eager to see how last year's females look after molting so I will know if any of them can be used again. Neither of the females from my starter trio (all three were all from the same hatch, and are likely "siblings") were usable after their first molt because their color shifted so much. That means I bred their offspring this year and am just hoping for the best here.
Luckily the starter trio male still looks pretty good and if he is still around next spring, I mated him with his daughters this past season, and I'll put him with his grand-daughters next season, probably, at least. The cockerel I used from last year's hatch (with the same set of females, all his "sisters") seems to produce more consistent-looking chicks than his sire, but so far it looks like they all have poor color. The next few weeks will tell me a lot about those birds.
Because I broody-hatch my chicks, and broody brood them, too ... I'm thinking wing bands next year, followed up by colored leg bands for marking birds I spot with certain characteristics.
At what age can I wing band the chicks? I like to let them out of their broody pen when they're about a week old. Sometimes sooner, sometimes later.
