Ok, still working on adding more runners. I am about to accept a job offer for a preschool teacher. I am NOT buying an incubator. But is there a way to incubate eggs in a homemade incubator? If so, point me in directions to get info. I'll bring it up with the lead teacher and see if I can do some science that way and then, oh, look, a few runner ducks need homes, why don't I bring a couple home! Oh, crafty I am lol I'd need to make sure I have homes lined up first though before we do it.
