I've searched the internet and haven't found any real answers. The past two years we've incubated a batch of our hens eggs and seem to have a very large rooster hatch. Last spring we hatched 42 eggs and 36 turned out to be roosters. Great for my freezer, not for increasing my flock. This year we set chicken eggs, slate blue turkey eggs and muscovey duck eggs. The only two ducks to hatch were both males, we have a larger than normal number of toms and it's looking again like our chicken hatch was heavily male. So is it just totally random that we have such a high male hatch every year or is there something we can do to effect this?
