Maleea,
The secret is not to put too many bugs in the "feeding tub" - as some dragons can freak out over that. I start with a handful, and when they eat those, give them more. The tub is easy to clean when done, and it can be used for other things (if need be).
Ahhh, brumating. It's not the same with all dragons. Some nap for days on end, while some have brief periods of alertness every few days. I offer greens once per week when they are napping - but I don't press the issue. I also give baths to the ones that are alert - but don't wake the ones that are sleeping. I keep a chart going during the winter months to keep track of who is doing what (but then, we have dozens...).
A good rule of thumb is not to force the issue... if they are alert and will take some food, ok. But if they want to sleep, I let them. I just watch for weight loss, and dehydration.
Take good care.
