I'm so confused! We candled the 10 or so eggs left under our momma. (She began with 20+ eggs from all our hens. She continues to sit even though she has 2 week old chicks running around her) One egg we were sure was dead as it looked like about the seven day mark. At the latest, it should hatch within the week. We cracked it open and were so incredibly sad to see a tiny LIVING chick probably with at least a 1 1/2 weeks left. How can this be? Is it possible that the momma couldn't keep all the eggs warm and some are developing super slowly????? Does it work that way? I've read that if an incubator is cooler than the recommended temp the chicks develop slower. Anyone got any ideas of what's up?
