Ok,, an update. We had four eggs rocking violently in the classroom on Thursday, Friday they slowed down. Since I can't be there to regulate the classroom temp and they seemed close to hatching I brought everyone home. No action yesterday, and since Friday was 21 days I got worried. At midnight I gave in an candled them, 1 showed a little heartbeat but a big bloody spot on the side. Two showed a little action in there and 1 showed nothing. Got up this morning, nothing. Went to breakfast and when I got home the one that showed no movement at all has a pip. Today is day 23 for them. The bator was holding steady in the class but the homemade cooler/hatcher had issues. After we moved them we had trouble keeping the temp and humidity regulated. I'm hoping we get at least this one more to hatch.
