I had a temp spike on Sat. night/sunday morn. Bator was hard to control all day. It has leveled out and is doing fine and I still have live chicks. Of 16 eggs, I know atleast 6 and possibly 8 are still developing and 4 are olive and I can not tell. I can see movement, so I know they are ok so far. I think two quit early, perhaps because of the spike. The other 4 never started from what I can see. These eggs were shipped and 12 had detached air cells. So they've been through a lot. If I were you, I definitely would not throw them out. I don't if mine will make it to hatch, but I see live babies so far so I'm holding out hope.
