Hi, I’m making a bed around the perimeter of my chicken coop and run (not for the inside). My chickens don’t free-range so they won’t be walking in it but they’ll be close to it. We have think grass in our yard and I’m doing this so I don’t have to get the lawn mower so close to the edge of the coop - and just to make it look pretty. I have edging and landscape fabric already laid out but am looking for suggestions of what to use or not to use for mulch. I don’t want anything to attract bugs so thinking of going with small rocks/pebbles but am open to suggestions.
