Ray,
A couple of months ago, I put a nuc, that only had a one inch entrance hole, on the ground and shook a hanging swarm into it. It also was so large that it did not fit in the nuc. I smoked them in, stapled wire mesh over the opening and took them home and dumped them in a full hive. It was only a 45 minute ride but more than of them were dead in the bottom of the box.
Bee careful.
I immediately modified 4 nucs with screen top and bottom boards so that that would never happen again. I recommend that at minimum you make up a screen top board to fit this hive and have another box to add to it so that when you take it down you can give them more space and let them move after dark and then you can add screen to transport them. You a red head lamp to work them after dark. Most of the bees do not see red light. I say most because I have had one or two react to the red light.
