>The guys that did the top bars said they died beacuse of the temps and no frames with foundation to cluster on.
Swarms have no foundation to cluster on. I install packages in foundationless hives often enough with no issues.
>They fed but the package just wouldnt get off the bottom and hold on to anything or climb.''
Maybe it was too cold to feed syrup. Once they are chilled and paralyzed from cold, bees can't warm themselves back up.
>How would you feed them during the winter ?
Winter is not the time to feed. Bees cannot take syrup in winter.http://www.bushfarms.com/beesfeeding.htm
> In a lang you can use a candy board and pattys. how would you do that in a top bar ?
In a lang I don't use candy boards or patties. But you can make a gap between the top bars and put a pollen patty on if you really want to, or put some dry sugar near the cluster and wet it enough to get it damp, or you can make a feeder to fit the top bar hive. People use everything from frame feeders to boardman feeders on the bottom, to baggie feeders on the bottom.
