I'm on the "same page" as the other posts: in the wild, snakes lay low when in shed; if they didn't, their poor eyesight might make them easier pickings for a predator, or more likely to suffer from other perils, while also more likely to fumble if they did happen to find prey. They've totally evolved to skip meals during a shed since there's no "room service" like when they're our pets, so don't worry at all about sticking to a strict feeding schedule. Meals get missed if you're a snake- it's all okay.
What's more, both digestion and shedding requires extra hydration from a snake's body, so if they happen to eat during a shed, sometimes they end up with a "stuck shed"- one that doesn't come off as it should, & may come off in a "million" pieces or require your help- it's not fun.Some snakes have no trouble doing both, but why push it? Yours may well be one that doesn't "multi-task" very well.
