Trust your gut and pull off the feed, they shouldn't be taking it anyways. I would have pulled the feed after the first qt or two since you had drawn comb.
There are alot of ways to open up the brood nest. Move honey frames up, add more drawn comb to the center, put an empty frame between 2 frames of brood, add a honey super. etc etc.
The queens maximum laying potential is somewhere around a deep frame every 2 days. So you should have about 10 open deep frames as brood nest. The rest can be honey and pollen.
