Can someone tell me more about these? are they like chickens? other than the button ones what are the most popular one? do they take a lot of work? What do people do with them??? Are the eggs and meat eaten (I know some are) , if so which is the best breed for that. I really have my hands full but I am curious, I have been reading treads about them and seeing them hatch and they are quiet cute. What do they require, is it pretty much like a chicken? Can they withstand the winters or do they need heat? do the males crow?
