Ok, I have one have and it looks like it overwintered well. My plan is to split the hive this spring if it contiunes to look strong. I've seen on other posts that putting a tree branch in front of the split hive gives the bee an orientation mark and helps to prevent them from drifting back to the original hive (if the hive is split and then kept in the same bee yard). Will this really work or is it best to move it a few miles away, wait a few weeks then move it back. Obviously if the tree branch method is as successful as moving the hive 2 miles I'll opt for the tree branch. Thanks for the input.
