My boy, Cosmo, just recently had his 5th shed with me.
He's been with me since March of 2017, so 5 sheds in 18 months. In that time he has gone from 11 grams to 72.
This is my only hognose, but based on that limited sample size, they definitely seem to shed less frequently than other species I've kept.
And my experience with feeding: Cosmo eats when he wants to and doesn't when he doesn't (lil' pain in my butt). Even at 70+ grams, he almost never takes prey off the tongs. I just let him know it's there and set it down. Sometimes he eats in 5 minutes, others it's still there when I go to bed and gone by morning ...and ovcasionally still there by morning...
