I think 12 hatched. I opened the rest of the eggs. Two of Betty Boops, my barred rock that we had to put down, eggs remained. It looks like one pipped internally and was ready to hatch but passed away. The other died and never even pipped internally. There was one other egg with a dead fully developed chick, also unpipped. All of the others looked like they were not fertile or quit very early on. One or two looked like they started to develop then quit. I’m very sad about Betty Boops egg. The one egg of hers that did hatch, the chick has super swollen feet and can’t walk. One other has super swollen feet and can’t walk as well. They were both very late hatches that I had to assist. I am just hoping they get better as the swelling goes down.
