Swarm bearding in the rain normal or just settling in?

[winevines]

Is it common for a recently caught swarm, put into a nuc box to STILL have a big beard on it- in the pouring rain at 10 pm?

Could it be that there is not enough room in the nuc box?

I put in all undrawn comb and a little bit of sugar syrup in a division board feeder

It is possible it is too small a box for the swarm. Check in the morning to see, or when you get a break in the rain.

If you have a full sized hive body, exchange it for the nuc. The division board feeder reduces the volume of the have also. 3-4 frames just aren't enough for a good sized swarm.
