Today I planned on opening my nesting boxes and when I went to prepare them I noticed some small, fuzzy, beetle looking insect. There weren't a lot and the strangest part is I can't find any in the coop (I had pieces of wood separating the sides). Im frantically inspecting the chickens, but don't see anything on their bodies or vent area. I'm going to take out everything and put in shavings. Can anyone tell me what these bugs are? Or even tell me what they definitely are not? Im also looking for recommendations on something I can treat the whole coop with. Thank you so much for your help.
