Does a colony feel cramped even with a deep of mostly undrawn plasticell foundation above them? Not normally. If they are predisposed to swarm they'll do it no matter what but adding a mostly undrawn deep on them will stop the urge for all but the most dedicated from swarming.
Should I get ready to do a split when I inspect later today considering these circumstances?? I would say in this curcumstance no unless you see swarm cells that are active or capped. I would be surprised if you see this though. However, I would say you should always be ready for a split.
Could a strong colony draw out and fill (pollen and nectar)six frames in 6 days? I've never seen it but give them two weeks with heavy flow at peak population and you'll have to add something.
