I feed all my F/T eaters in their tubs, and two of the picky live feeders who only take small mice, but all my live rat feeders get fed in separate bins because I've seen one too many pictures of rats going after snakes, and its easier to watch them and make sure everything is okay. The only other bonus of feeding out of their normal cage or tub would be that its easier to do poop patrol and fill water and whatnot while they are eating.
I used to feed all of them in separate bins and it really just wasn't worth it. It was a pain to move them all the time and making space to put the bins and yeah.. not worth it if you have a larger collection..
