Re: a few qustions from a starter
As mentioned by Andrew you need to deal with the comb issue and not ignore it, it's not going to go away on it's own and will only get worse over time. The bees are not going to like it but it's one of those routine procedures which we need to stay up with. When you get to the center of the brood box a couple puffs of smoke between the frames will help clear it of some of the bees so you have room to work. If it's really bad you may need to cut some of the comb between the top bars to be able to pry the frames apart without a lot of tearing. I like to use a serrated bread knife for the cleanest cut. Trim the wacky comb and put it back together, the bees will take care of the rest.
As far as continuing to feed, that's a local judgement call. Are they still drawing out comb? If they are, and your flow is light, then you could keep feeding. Do they have plenty of syrup stored up? If so then you may want to stop feeding for a while and monitor closely any changes in their stores. If they burn through it quickly you can always start feeding again.
