I would like to try incubating a batch of eggs this spring. The flock I have now is my very first, and I've had them since they were 1 week old. The big question is, where would I start? How would I know which eggs are fertile? Which eggs would I choose? When are they put in the incubator? I need the beginners lesson! Here's the flock. Roo in the back has feathered legs and a black tail. The 2 closest to him are EE's/Ameraucana - partridge/ light brown (blue egg), and black (green egg) Light colored hen on the far right is just a mutt. She has muffs and lays a pink/apricot egg (almost the color of her) The 2 in front are gold sex links.
