bee orgy?

[hoku]

I knew that would get your attention!

But really.....so I was checking on a new hive that is at week 3 of a trap out.  It was dusk, and there were bees covering the entire landing board.  They were not fanning or bearding, but seemed to be crawling all over each other, non-aggressively.  Some were even standing on top of each other for awhile.  They seemed to be mostly worker bees. 

I am a new-ish beekeeper and have never seen this before.  What are they doing?  Massage?  Bathing each other?  Anyone know?   
thanks, Wendy

I'm no expert, but I believe these are worker bees that have just finished a days work and are hanging out for a little rest and relaxation before turning in for the night. :-D

Is the box too full for all of them to get inside? It sounds like normal bearding. They need more room. Add a box or remove that one and start another with fresh eggs and larva.
