My chickens started roosting on top of the chicken coop and there is poop all over the top of it. Well what is unusual that I've never seen before is these bees. I don't know if they're bumblebees (I've never seen a bumblebee in my life.) Or wood bees. And they look like they're gathering the chicken poo up and eating it? Taking it somewhere? I don't know. I've never seen bees do this before.
