I have not bred poultry or birds at all yet, but I have some experience in hamsters and dogs. Everyone has their own opinions, if you look up bully dog breed pedigrees on bully Pedex (pretty sure that’s what UKC breeders reference) you will see a LOT of heavy line breeding, like 6x Bolow or 5x DAX, that means how many times that particular dog appears in the pedigree. I think pedigrees usually track maybe 4 or 5 generations on the actual paper, and you will see father to daughter than that father to the offspring again etc. I think this style of breeding is what causes a lot of mutations that outsiders blame on crossing in other breeds, but I think it’s more nefarious than just lying on paper, I think the inbreeding might make one dog at the end of 5 generations that they think is great, but a many more unhealthy and crippled dogs.
In your situation what I would do is band all your birds. Breed one male to a specific female group, then breed the other male to a different group of hens. Cull all male offspring
the next generation after that, you would breed those offspring to the opposite male. then cull the original males and keep one male from each of the current generation you just hatched. Your original females will be getting older by then so you will cull them when their production starts to drop.
It seemed like you wanted to keep your males as long as possible, but they mature quickly so your time frame is flexible, but make sure you start making the next gen before yours get too old, you want to make sure both males are producing in order to get a wider gene pool.
to make your life easier you will eventually want to inject some new genes. Often you can find people giving away extra Roos for pretty cheap and you could bring some new blood into your program.
here’s some good info on dog genetics, I assume the inbreeding coefficient of over 5% would probably be equally risky in most animals.
