So the last three eggs are on day 24. There are no pips, no cheeping, nothing. I tried to candle the other night and saw no movement. One was solid dark. Two had definite air sacs on one end. All three are under mama so I haven't been messing with the incubator. Should I give up? As long as there are eggs mama is going to sit. I feel like I should take them away so she can focus on the the four that did hatch. Any thoughts?
