Hi everyone I’m new to chicken keeping, and as I was cleaning out my coop this morning I noticed these tiny black bugs they are less than a millimeter and there is hundreds of them, they are all under the perches and there is some in the laying boxes. I have had this problem before and treated it by doing a full clean out of the coop especially the effected areas then put new bedding in and sprinkled DE everywhere and mixed it in. I have no idea what else to do.
