The one that pipped early died. Its membrane around the pip turned an ugly brown and was getting no further than the same exact spot so I took the egg into the steamed up and hot shower room and chipped a half circle and carefully ripped the thickened brown membrane where there was no vessels and put it back to kick out on its own. It finally did but it was obvious that its little legs and toes were turned bad (it also may have been malpositioned) and I decided I better get ready to do some more "chick shoes" soon but he only lived another hour. It looks like he may have snagged his yolk sac when trying to get out. It would have been a beautiful Silvery white one with jet black skin. When I hatched duck eggs last Spring the same thing happened and I did NOT help it get out and it drowned in the yolk. The membrane around the pip had turned an ugly brown where all the others were white as they came out. In any case, the 5 I have now are white, silver, blue, and one possible partridge (but I have no idea where that color came from) Here is one of my vaulted headed ones...
