Hey Casey! I find Hogs often lay poorly calcified eggs.
I've been breeding them for maybe 15 years, and I have more problems with
hog eggs than any other colubrid.
The strange thing is often eggs that look like slugs are in fact fertile.
The problem is keeping them from falling apart before the neonate emerges.

I had a female give me 47 eggs in one month last year. (two clutches)
The season before, she ovulated in brumation, and ended up laying eggs sporatically
all summer long. Most were no good.

I've started using Repcal on all hog meals post brumation. I think it helps with calcification
but I wouldn't swear by it. This year once again, I got a clutch of less then fully calcified
eggs. All were fertile, but all will not hatch. Some are half covered with mould, but still the embryo
lives... It's rather strange... Maybe these snakes need UV.... Sounds goofy, but something is going on when eggs are fertile but
aren't properly shelled.
