OK at the moment, the incubator is one we've had for years and we've always had 80-90% hatch rate with our quail sometimes more, but we've noticed it has a less than 10% hatch rate for anything bigger. We've tried it a few separate times for turkeys and chickens and the chicks will either stop developing halfway through or will start to hatch but die right before they make any real progress. I was wondering if there was a brand that any of you know of or use that seems to work really well for chicken eggs? I'm at work at the moment and can't think of the name of the one we have, only that it is made of a thick Styrofoam, is still air, and has a metal mesh bottom. Thanks!
