I have 1 rooster and 2 hens (Javas), and I plan on hatching some chicks soon. The 3 that I have currently came from the museum. Once I hatch some chicks, I plan on keeping the pullets and selling off/butchering the boys.... but then what about next time I want to hatch some chicks? Is it okay to hatch chicks from a hen that was bred w/ her own father? Do I just need to get a "new" rooster every few years or something? How does all that work? Thanks!
