I have a flock of 17 chickens that are about three and a half months old. Some I bought from a breeder (black australorps), and some I hatched from an incubator from eggs from my grandmother's flock. Right now, I see that I lucked out - only five of them turned out to be roos (the rest are pullets). Three of them are roos from my grandmother's flock, and two are from the breeder. Here is my dilemma. The black australorps I bought are very good layers and broody hens, I heard. I would like that in my flock, so I should probably keep one of the roos from the breeder, right? However the rooster that is on the top of the pecking order is one of the ones from my grandmother, my only white one. He's the largest, he grew the fastest, he's the fastest pecker, etc. Plus, when I let my chickens out to graze, he's the one that's most responsible, always looking around and being the first to alert the chickens. He would be an awesome rooster to keep. So here is my dilemma - should I keep one of the Australorp roosters, who are both not as good roosters as my white one, for the sake of preserving the breed, or should I keep the good rooster, (who will be very useful to us since we live in a kind of wild area - lots of raccoons, a fox, many hawks - I've already had two chicks stolen.) ? Thanks.
