My update: The last one that hatched around midnight had a herniated navel, about the size of a pencil eraser. I put a little triple antibiotic ointment on it and pulled the two earlier hatchers out to the brooder. That first crazy Orloff was walking all over everyone, and I wanted the navel guy to get some rest!
I had 4 out and 2 pips at 4:40 this morning. Need to go see what's up in the incubator now.
