So if 1 rooster can change the dynamic of a flock, can the roo be housed separately (until needed for breeding) or does that make for an unhappy roo?@Happy Novogens I have heard of broody's before that did not sit the full time on the egg's to hatch them. I have also heard of hen's that kill the chick's as they hatch. I incubate in an incubator because with knowing that, I do not trust the hen's to hatch them. It only takes one rooster to fertilize the egg's, unless you are planning on running 2 group's for breeding purposes.
