Have any of you done winter feeding of a TBH?
I know that in principle one shouldn't need to feed a properly managed hive. But when you must, how do you do it?
There's no obvious way to get food directly to the cluster, since the bars prevent access from above, and you don't want to be moving combs at all.
I've tried fondant, set just beyond the last comb, inside the hive. Do you have experience with other approaches?
