I've lost count of the days now (probably 25 by now). I had a single chick hatch early, but it died the next day. Temperature is around 100 F, not sure exact humidity but I have the Hoverbator with the sections for water to create proper humidity. I've had a couple eggs get splits in them and start leaking---anyone know what causes this? Some of the eggs feel heavier than the others, like there might be a chick inside. Is it time to throw in the towl and dump them??
