Ok cool. If I can make a suggestion, I would say to read over the stickies on this forum on how to properly set up your enclosures. I'm guessing since your heat isn't regulated in your BP enclosure that your corns enclosure is also not regulated.
I honestly can't stress enough how important a thermostat is. If you care to search for snake burns online, it may open your eyes.
I'm not trying to sound rude, but it sounds like you've still got a bit to learn. We were all new once, so I understand, there is a lot to learn.
It's important to check your temps, etc... much more frequently than once a week.
Yes, snakes do burrow and your snakes are, in fact, touching the glass surface. Corns generally like to burrow more so than BPs. You ensured me otherwise, but the facts are snakes burrow and an inch of substrate isn't going to stop your snake from touching the glass with ease.
Your temps and humidity are both off a bit.
And yes, the eye indentation is a pretty simple fix. Despite what your breeder says, it is not common unless your husbandry is off. I've never had a snake with dented eyes...
I'm not trying to insult you or come down hard on you. I just truly want what's best for you and your snakes. The quicker you get things right the more you can stress less and enjoy your snakes. And I promise, once you have things dialed in it gets much easier.
Also, having a little cash stashed away for an emergency vet visit or malfunctioning equipment is always a good idea. If you need a hide in a pinch, a simple plastic bowl or from the dollar store or a butter tub with an entrance cut out will work for now.
Good luck! We're here and happy to help if you have any more questions...
oh...and again, I highly recommend unplugging unregulated UTHs
