Normally I would say no they will not swarm at this time of the year but you have been feeding them and the bees think there is a good flow on. That changes the answer. If you have full hives I would stop feeding or at least reduce the their feeding by only giving them a few holes.
If they swarm, they will seriously weeken the hive for winter.
Jim, I did not feed them yesterday. I am hoping they won't swarm on me, because I plan on using some of those bees to strengthen my weak hive. How long after making queen cells do colonies swarm? (7-12 days?) I want to know so I go back in before that and possibly manage them, not to swarm. Open the brood, checkerboard and add another box. I'm not even sure they have queen cells though as I didn't look at any frames so it would be a guessing game.
Normally when bees cap the queen cells, the hive will swarm. Remember, queen cups are beeing made all the time, a queen cup becomes a queen cell when it has larva in it. Checker boarding is an excellent way of keeping them from swarming. The bees need need a place to build wax and the queen needs a place to lay eggs.
Look under the brood boxes for swarm cells.
