How Often Should I Clean My Chicken Run?
How Often Should I Clean My Chicken Run?
For most backyard flocks, a full run cleanout every one to three months works well, with lighter maintenance in between. According to Penn State Extension, the frequency depends on flock size, run size, bedding type, and weather conditions, but the goal is always the same: keeping ammonia levels low and the ground dry enough to prevent disease.
The biggest variable is your bird-to-space ratio. A small flock in a large run needs less frequent cleaning than a larger flock in a tight space. Our mixed flock in Boulder Creek has a 35-by-15-foot enclosed run, which gives the birds enough room that waste does not build up as quickly as it would in a smaller setup. Even so, we do spot checks weekly and a full bedding replacement roughly every six to eight weeks.
Between full cleanouts, there are a few things to stay on top of. Remove any visibly wet or heavily soiled bedding weekly, especially around waterers. Ducks are particularly messy with water, and wet bedding is a breeding ground for bacteria, mold, and parasites. If you can smell ammonia when you enter the run, you are overdue for a cleaning. UC Davis Veterinary Medicine notes that ammonia buildup can damage poultry respiratory systems and increase susceptibility to disease.
Your bedding material matters. Straw, wood shavings, and dried leaves all work, but they decompose at different rates. Wood shavings absorb moisture well and last longer between changes. Straw compresses and gets soggy faster, especially during our wet Santa Cruz County winters. Dried leaves from fall cleanup are a free option that works well as a base layer, though they break down quickly.
The deep litter method is worth considering if you have the space. Instead of removing all bedding regularly, you add fresh material on top and let the lower layers compost in place. When managed correctly (turned occasionally, kept from getting too wet), deep litter generates mild heat in winter and produces excellent compost. Cornell University's poultry resources describe it as an effective approach for small flocks, as long as you monitor moisture and ammonia levels.
Whatever method you use, the cleaned-out material is garden gold. Chicken and duck waste composted for three to six months creates a rich amendment for garden beds. Do not apply it fresh, since raw poultry manure is too high in nitrogen and can burn plants or introduce pathogens.
This week: Do a smell test in your run. If you can detect ammonia at bird height, clean out the bedding this weekend. Set a calendar reminder for your next full cleanout based on your flock size and setup.
