Bees still doing well

I've been feeding them a quart of 1:1 sugar syrup every other day.  I want to make sure they are doing well, but I also want them to get some of their food elsewhere so they get more complete nutrients.  The foragers keep bringing in lots of pollen so I know they have plenty of protein.  They haven't really been working on new bars lately, but they have been filling out the existing bars until there is just bee space between the comb and the sides.  Their numbers look like they have been building up, which makes me feel a little more comfortable.  They have about 8 bars of comb now and two partial bars filled out.  If they finish out those and maybe a couple more bars, hopefully they will be ready for the winter.
