Okay so I've been letting my naked neck and mini Cochin hen take turns brooding the nest. Or rather they've done it on their own, no help from me. So today I set up the bator for another batch and decide to see what going on in that nest since no live chicks as of yet. Anyway one egg on the ground and one egg pushed WAY to the side both VERY light, weight wise, and covered in feathers and old yolk. I figured both are duds but when I candled I just see black. So are they duds and should I just toss them? One of the eggs I took looks like it has no air sac and it's yolk just roles all over and the other has an air sac, great one actually, but I don't see anything looking even veinish or chickish in it. So with those last two should I still leave in the bator a bit and see what happens or are the both duds too?
