> 1. Do you have any suggestions on closing and moving bees using trailers.

The easiset way is to use a smoker and the bees will move in very quickly.
Many years ago I used to use the water method but it did not work as well as
smoke.  Some will say to move open entrance but if only moving a few hives a
short distance, I still shut them up as it saves the discomfort of those
stings when unloading.  When using a trailer, the hives tend to bounce
around more than with a regular vehicle that has springs and so the bees are
not very happy when you arrive at the site to unload them.
