No worries . Not one of my Ball / Royal pythons will show any interest at all in food whilst in shed . Most of my others don't either tbh . Probably the a few of the King snakes are exceptions to the rule .
It will be perfectly fine whilst you are away . They usually go and hide away for a few days , whilst in shed mode - maybe a week or more then they're fine .
The eyes stay blue / milky colour for a few days then the eyes clear and the snakes get their normal colouration back BUT they don't actually shed for a few days after they clear !
Just keep your humidity fairly high for the next week or so . I make a point of spraying the vivs a times a day as soon as the eyes clear and that more or less guarantees a perfect shed .
Once you've seen the shed ( usually found in a messy, rolled up ball in one of the hides ) you can try offering food . Always best to offer in the evening , with low lighting - in my experience - as they're nocturnal as you probably know ..
Just keep posting any worries or concerns in here plus maybe some photos ...
