I went out early just at daybreak it was still dark because of heavy cloud cover and I found about a dozen of these beetles on 3 hives. They are gray in color and about 1/2 to 5/8 inch in length are they something I should be worried about?
Small hive beetles are rarely half an inch long. I am not sure what those are. SHB are usually found inside the hive,the bees tend to corner them up in the top corner of the hive, just under the inner or outer cover. They are maybe 1/4 inch wide and 3/8 inch long.
