Thanks for the replies...
I just shot a skunk last week.. my Jack Russell had tracked him under a stack of RR ties. Trapped/killed 5 racoons last year.. they would come into the barn at night and climb up into the rafters and eventually killed a dozen guinie hens and a dozen chickens.. one was bigger then my dog.. he bearly could fit into the trap!
No scratch marks or such around the hive entrances.. the outside dogs sound like a good working solution.. but I'm feeding a small army right now.. 2 dogs, 5 cats, 13 steers, 35 chickens. The bee's are least expensive livestock I have.
I went down early this morning before daylight.. found half a dozen drones in front of one hive that had been booted out.. guess my "bee eater" hadn't stopped by.. I'll keep a close eye out for entrance damage.
