Justin, I assume that you still have a flow on there right? If so there's no need to feed. They're bringing in plenty. I would get in there and check things out though. They may be making a mess of things. My general rule is I leave a swarm alone for about a week or less depending upon what kind of comb guide they have or if I'm using foundation then I'm not too concerned. After a week I check to see if there's a queen, what the stores look like, what the comb looks like etc. Then I go from there. I caught a swarm last week that the queen seemed very small. I thought she could have been a virgin. So I let them go until a week and they're drawing comb very nicely, but there's no brood. If I still find no brood this Thursday then I'll add a frame of eggs to this hive. This is my process. I hope this helps. Oh the swarm that I checked had plenty of stores already. Nothing capped, but several - most of the 7 or so frames had stores in them with some empty / open space on the bottom of the frames. (I'm using foundation less / comb guide frames)
