I searched for the answer, but couldn't find exactly what I was looking for...sorry if it's been asked and answered.

I currently have 2 deeps full of brood, pollen, etc...and 2 medium honey supers, 1 of which is nearly full. Should I inspect the brood boxes to see if they have enough room? And what's enough room....2 or 3 drawn but open frames for her to lay in? If 'crowded', should I slap on another medium for the brood?

This is my second year and they were fine in 2 deeps last year over winter, but I don't want to overcrowd them if I can help it nor do I want to give them too much space for winter.
