Re: Little Worried - Need some opinions.
You showed six frame pictures, and from what I see on those six frames, that hive is almost starving Dead. The only stores I see is some traces of capped honey here and there at the edges. You adding two frames of brood above an excluder, frames that you had shaken off all the bees. This hive doesn't have enough bees to cover that brood, from what I see of the pics you posted, and the brood will most likey die the first night/day. If you want to save it, do reduce it to a nuc and give it feed, both syrup and pollen sub. Us an inner frame feeder and hope it does not cause it to get robbed out. Otherwise, as Michael said, this hive looks dead.
