How do you keep the smell out of your duck pen?

To keep the smell out of your duck pen, regularly clean the area by removing droppings and soiled bedding. Use a deep litter method with straw or wood shavings, which helps absorb moisture and odors. Additionally, ensure proper ventilation to reduce humidity and allow fresh air circulation. Finally, consider adding natural odor absorbers like baking soda or diatomaceous earth to further minimize smells.
