Checked on these last night and didn't see any signs of anything. As a matter of fact I've been worried as these are some of the biggest eggs I've ever seen. Easily a third larger than Tepin's average egg size. Imagine my surprise when I checked this evening and there was not only pipping eggs, but one completely out! Big babies that will probably weigh a couple more grams each than the other ones. Nice markings on the first one out too.
