I know the craft store Michaels sells a pour-on type of acrylic sealer, I wonder if that would work?
I had one baby cornsnake die as it hatched I fed it to my savannah monitor. I don't breed larger snakes, just the corns. I recently was given a king snake who my friends couldnt get eating(he eats fine for me) so he's a back up for DIE's as well. So the ones that don't make it become feeders. I would rather see them help another animal thrive then rot. I may pic up some of that sealer and try to preserve one next season, that is if something hatches kinked, deformed or DIE.
