Here is a link to our latest YouTube on how to clean out your chicken pen.
We think that at least every 3 months chicken pens need a good clean. We move the chickens out for the day while we clean their house. We remove the items from the pen. Remove the old bedding, spray with Maldison 50, dust with disinfectant powders. We then replace bedding, perches (which we dust for mites) and return feeders nesting boxes and water.
You can purchase the items from our online store. https://evans-chickens.square.site/
