Don't worry, but start weighing them at least on a weekly basis to monitor any drastic weight loss. You will need some type of scale that will go down single digit grams. It seems as though that the number 1 issue with hogs not eating on this forum is when people bring home juvies for the first time. So this being a typical situation and only 3 weeks worth of anorexia, it's nothing to worry about.
Do make sure the temps are high enough, at least in the 90s, and a good temperature gradient to room temp. Provide plenty of hiding spaces. If they are housed together, separate them into their own 20 gallons. Limit handling to only a few times a week. Also try scenting with regular flavor tuna, or even a red spotted newt red eft.
