If it was me, hive #2 with the queen that has damaged leg, quit destroying supercedure cells and let them replace her.
It is the time of year for queens to start slowing down egg laying. Feeding might help to pick them back up some if they have room to lay. Constant feeding might help to get them to draw wax, but it is getting late in the year now. I'm in California, and with constant feeding, I've had strong hives build wax into October here.
Live life with gusto, having no regrets, being thankful every day, and cherish each moment as it happens.
