I'd say she's pretty settled in

I have to agree with everyone. Moving a retic in feed mode isn't safe after they get to 8 feet or so. Besides, that logic can be flipped. You said you're going to take him out to not associate his cage with feeding, but then he'll associate being taken out with food.

Best bet is to build or dedicate a door ONLY for food. Problem solved. Use tap training or the rub of a hook to break feed response before handleing(if need be) and no issues, as long as you do it the same way every time they'll know what's going on.

Edit: I'd only feed one of those rats every 5 days for 3-4 feedings then you can probably go to smalls.
