3/4" holes in second deep. Plug-em or let it fly?

[Moon]

Going into winter I punched 3/4" holes in all my second deeps to provide an upper entrance in case the lower one plugged up with dead bees and also to help with air flow to prevent any condensation forming. Now that it's spring time again should I plug this entrance or just let it go?

I started with second hand hives. One of my bottom deeps had a 1/2 to 3/4 inch hole about two inches down from the top. I then knew even less about bees and decided that if the previous beekeeper used the hive that way, that I would leave it the same. It has been that way since last April, and more bees use the that hole than to the bottom entry. The hive has built up nice this spring, so if the bees are OK with it, so am I. I think I would leave the holes alone.

I have entrance holes in everything except supers. Bees love 'em.

I have holes in most all my deeps - the bee use them and seem to like them. I cover all but the hole in the up-most deep for winter using duct tape. My holes are 7/8".

Ok cool, thanks for the replies. I guess I'll leave them then.

My bees plugged them with proprolis. They had their own reasons, so I let them do what they wanted to do.

From what I've read the holes in the upper deep speed things up a bit for the bees, saves them from having to crawl up from the bottom deep!

I leave mine open except during "robbing season."
