I had 3 pipped, one bad pipped on the back side (down side) of the shell. I should have opened the bator and turned it. but I kept tellingmyself, leave it alone, well after seeing nomovement since it first pipped, I quickly reached in and turned it over, nothing. No beak movement nothing at all. It had such a big hole pipped, I let the humidity get up again and quickly removed the egg. It was a fully formed Phoenix, still had a little yolk attached, but dead dead dead.
