Okay, so I have 40+ chicken eggs in my incubator, and my dad gets three duck eggs. Turns out they were rotten, but we kept them in the incubator for a while just to be sure there was nothing growing inside them. Well, its about 2 days after my chicken eggs were scheduled to hatch and I'm wondering if the rotten eggs might have killed the chicken eggs? I dont have any way to candle the eggs, and I dont want to break it open because I'd feel bad if I killed one. The next group in the incubator is scheduled to hatch on the 25th. I was planning on these eggs hatching too, because I have a non-rotten duck egg waiting to go in, and I need a spot to put it.
