How do you keep the mulch and sand areas separate, or did I just not see it in your pictures?i make a blend of 16 chicken safe herbs and dried flowers for the coop and nest box. I do sell it. Smells yummy.
Sand in the front as i can get wet and acts as an indoor run when they dont want to go out. Mulch in the back treated as indoor dlm. Moved to the overdoor run which is also dlm, every 4 months.
