Having your own chickens is great. There is nothing that tastes better than a freshly laid egg in the morning! But, chickens can get gross. And they get gross fast. They require constant attention: above and beyond just feeding and cleaning. Coops can become health hazards for both you and your animals if you let it slip for even a day. This post by Jill at The Prairie HomeStead has a tutorial on how to keep your coop clean and disinfected the natural way:
First, shovel and scrape all of the manure, dirt, shavings, cobwebs, and feathers out. It
Next, take a hose to it! Give the walls, floors, roosts, and nesting boxes a good spray down
Next, mix up equal parts white vinegar and water in a bucket OR just slosh straight vinegar onto your wet floor. I preferred the sloshing method personally. Then take your broom or brush and give everything a vigorous scrubbing, making sure to distribute the vinegar solution as thoroughly as possible.
