I had 10 blue copper Marans eggs, and then some EE eggs from a BYC'er here that had beautiful birds. Nothing. I haven't hatched for over a year, and granted, I just got the incubator going again (Brower top hatch) and they were shipped eggs, but still, nothing. I had some temp drops (power outages ) and a few spikes; kept water in the incubator, though I was not monitoring the actual humidity. I have yet to open them up, but I do know there was some development (more so in the EE eggs, then the Marans eggs) I can't afford to spend $60+ and get absolutely nothing, so I'm packing the stupid thing away and I'm seriously tempted to throw it. It's my own stupid mistake for buying eggs I guess-no chickens of mine to lay, but maybe I should have tried to find locals first, before I tried to go with breeds I wanted.
