My father in law just called and said there are bees piled thick on the whole front side of one of my hives. This is a new hive (this year) and they seem to have room in the hive (just put a honey super on last week). He said he see bees coming in from the northwest....not coming out of the hive. Could I possibly have a swarm that is coming in to take this hive over? Is this robbing or is this hive getting ready to swarm?? Any thoughts would be appreciated.
Thanks.
Thanks.
