My Cochin has been sitting on 3 eggs, 2 Ameraucana eggs and 1 mutt egg. I went out this afternoon, and found her on the wrong nest, UGH!! I checked the eggs and they were still warm, and as I was checking them I discovered a pip with the beginning of a zip on one of them and I heard chirping inside. I moved her back on them, and put a board up on the nest box, so that the chicks won't fall out. Hopefully by tomorrow morning I will have at least 1 new chick if not more.
