I have a question! I'm using the Brea Mini Advance incubator with 7 chicken eggs. *stupid me* first time ever trying to hatch chicks and didn't realize the bator had a water well. They didn't get water inside for humidity until day 7. I am now on Day 14. I have a mixture of brown/green/white eggs that I purchased from a local farm. I can only see through the white ones. Can't even see the yolk in the others. The temp was fluctuating for the first couple of days, but I insulated the bator with a sweater and it has consistently been 99.5-99.6 ever since. I didn't want to give up on them so today (day 14) I candled the white eggs again. The yolk seems a bit bigger and so does the air cell. But I can still see through most of the egg and I don't see ANY blood vessels. Or even a dark spot where the chick might be starting. Is it time to crack one open and start over?
