I have a broody hen setting on three egss. I didn't let her keep more, as it is brutally cold and this is her first effort. The first couple of weeks, she would get up and eat. then she switched nestboxes She has been in this one for about 2 weeks, but she never gets up to eat. Nor does she (seem to be?) turning her eggs. How are they supposed to do that? Meanwhile, in the house, I have 30 eggs in my bator. I turn them twice a day. I have an X marked on one side of the eggs, but the next time I go to turn them, it seems some have rolled. What gives? The incubator is on a level surface-i even checked with a level!!
