I did the eggtopsy just now. The egg with the weird floating stuff was clearly rotten, but the other egg in which it was hard to see....there was a perfectly formed chick inside, with its little beak poking out of the membrane, stuck in that position. I never saw a pip in the shell, either by looking or by candling. I don't know what happened, I wonder if it was rolled like the other Buff Orpington and couldn't get a hole out? I can't help but think if I had candled it earlier I could have saved. it.
