Re: Inner cover burr comb
I don't get around and into a lot of different beehives like I used to, but isn't the "standard" inner cover a sheet of thin plywood w/ a hand hole in the middle, what Brian calls a feed hole, inside of a wooden frame? One side of the inner cover is deeper than the other, isn't it?
I guess I have seen ones that are flat on one side and indented on the other side too. So I guess there is some variety in the way inner covers are built.
I don't know why anyone would be surprised that Brian has only seen the one kind. Try educating instead of criticizing.
Brian, the use of a flat sided inner cover won't really kill any more bees. Not if one smokes them down between the frames before putting it on. Regular hive manipulations kill bees, but not enough to make a difference to the colony, usually.
If one has an inner cover w/ a deep side and a shallow side or one w/ a flat side and a deep side you can avoid burr comb build up by putting the flat side or shallow side down during the honey season. Then flip it for the Winter so bees can more easily move up over the top of the frames over onto honey. Makes space for a protein patty, if you use them.
