So, I'm new to the whole hatching chicks out. I just hatched my first 3 ever. Before this I've always just ordered from a hatchery and I've always had really good luck, but I have to tell you that incubating eggs is a total addiction and I'll be doing lots more I think. The ones I've ordered have always been sexed (and other than one mistake they made) it's always be spot on so I really don't have any experience in trying to figure out which is a rooster and which a hen......so, how old will they be before I can make a reasonable stab at it. One is a Wheaten Maran and the other two are Americauna....they are all pretty cute, I have to say.
