my incubator has a plastic mesh floor it does have small square holes but the day I take the rack out I put down paper towels so their feet do not go through. I do not believe they are imbred, I get all my eggs from a licensed breeder. He said he thought they could just be hatching too early but still I don't think I would have 1 every time hatch early. I bought a new thermo/humidity reader to make sure that isn't the problem.
I get this once in a while with chickens and Bob Whites. I believe it's like any other creature, Their is usually a runt in mammals, or a leg,tail, flipper, or tooth issue. SO, that being said, all eggs aren't going to be perfect. Maybe they didn't turn into position right and their feet are curled. Like any other creature, not all are strong and nature must and will weed out the week. We try to make them all perfect, that's our nature as humans. "CARING". Nature is harsh, it has to be to keep the gene pools the best quality possible, so the week, the deformed, the one that lags behind, WILL be dealt with in one way or another. I won't let it last long, if the problem persists, I put the animal down. It just wasn't meant to make it, and wouldn't in the natural world.
