So, I've only had 5 clutches laid here? But none of them had any stuff attached. Yeah, you get placental goo with boa live births, but python clutches are very clean.
But I've also never had an egg bound female. It's definitely good that you got that slug out of her, you probably saved her life. But the attached stuff worries me. I've never seen that, never heard of it coming out with the stuck egg in an egg bound female, so I worry that she might not be out of the woods. That blood could have come from someplace deep, which is why I'm jumping to antibiotics. I'm hoping one of the more experienced breeders here weighs in, someone who's had an egg-bound female.
In the meantime, I would shoot an e-mail with that picture attached to the Barkers at VPI: vpi@beecreek.net
