This is my first spring/summer getting my sustainable homestead up and running. My goal is to start with four heritage dual-purpose breeds that will breed and produce replacement chicks the natural way by next spring. I am not looking for show quality or SOP birds, but don't know if one of my SS pullets should be used as a breeder. I started my flock off with black Australorps to so as to have some good layers up front. After I got those near laying age, I decided on the other three breeds based on broodiness, egg laying and large size for meat chickens. I chose speckled Sussex specifically for the broodiness and large body size, especially roosters. My other two breeds are barred rocks and buff orpingtons. I ordered my chicks from Meyer because in mid-July they were the only hatchery with SS available. On hatch day, the hatchery had a "incubator disaster" and most people had their SS order canceled, but since I had ordered and paid two months in advance, I got my five straight run. My 11 barred rocks (7 pullets/4 roos) and five BO's (4 pullets/1 roo) were fine, but the speckled Sussex had problems right from the start. Out of five birds three are roosters and of the two pullets, one of them only has one eye. At 10 weeks old, two of the roos are so mean, I don't know if I can keep them until they are big enough to eat. As you can see, my careful flock planning is about to go out the window. I know if I was trying to breed show quality the one-eyed girl would be culled. Since my goal is to have healthy heritage birds for a sustainable flock, I don't know if the eye thing might carry over or if it is a result of a hatch gone wrong. Since I will not use the two mean roos for breeding, I am only left with one roo and two pullets, one of them with only one eye. It appears to have an eyeball under a lid that doesn't have a slit so the eye can open. She does as well as the other SS pullet in all ways. They are the same size, none of the other 20 chicks picks on her and she holds her own getting her share of treats, so the eye does not seem to be a hindrance. My problem is that I know nothing about genetics or about what physical defects could be passed on to her offspring. What would you do?
