I will say that I dont think that there is any reason to move him to a separate feeding container. I would try feeding in cage.
Yeah I've definitely been checking husbandry every other day- everything is perfect. I'm going to just try & feed him in his enclosure tonight. Thanks for the advice & peace of mind.

Also feeding in the enclosure is no problem, and seems to be preferred by picky eaters. And yeah 22 days is no big deal, unless the weight starts dropping off quick don't worry about it, just keep offering on a schedule.
I actually feed him "small" adult mice- 15% of his body weight. I'll try two pinkies that add up to 10 g next, my female mouse recently had 8 babies. Thank you for the advice! Many blessings!
