Very very few cockerels are needed, or wanted, in a home flock. You've gotten a lot of good advice, and I'll add mine. At most, keep the best male of the two boys, only if he's a bit better than his sire. I try to keep a good cock bird and a cockerel for each of my three breeding groups, as long as they all get along. This gives me a 'spare' if something happens to one of them. By spring, I sort down to one male for each breeding group, the best one. My Belgian d'Uccles, a small flock I've had since 1993, will get an added pullet or three every few years, to manage inbreeding. Think about your goals and plans for your flock, and manage them to move toward those goals. Over time, plans change, but try to have a plan anyway. Mary
