Re: Lots of syrup in cells, very little brood, advice?
Water it down more so it's still stimulating them but not clogging up the hive. Also if there's a lot of pollen it could be that they are also collecting nectar and your feeding is just adding to it they are jamming out the queen with stores. To test this you can stop feeding completely and see how they go. Also, move the frames apart in the middle and put an empty frame of foundation slap in the middle of the brood nest, to create more room for the queen to lay.
