I am looking at another batch of eggs to start incubating. I really love these wheaton marans I found on Gabbard Hatching Eggs website. My question is (and I really hope I'm asking in the right place!) if I buy a half dozen or so from her, and hatch the eggs successfully, and they grow up and I want to hatch eggs out of them, *takes a breath* do I need eggs from someone else as well or can they be bred to each other and hatched out? Thanks!
