I have the opportunity to acquire some Hungarian Yellow chickens. These, being the Canadian birds, all descend from one flock and I would be getting eggs from a smaller sub population. I will be (hopefully) getting 4 dozen eggs, but they would be shipped from far away and the usual rule of thumb is to expect 25% hatch- so I'd probably be starting out with around 12 individuals at most. The opportunity to add new "blood" is limited. Does anyone have any advice regarding the best breeding strategy to ensure a healthy, thriving flock? I do have a copy of the Hungarian Standard and Lamon's Mating and Breeding of Poultry but that's it and my experience breeding and selecting chickens is (extremely) limited. Thanks.
