Chicken Coop Disinfectant Recipe - orange peels steeped in vinegar for a month, then put in a spray bottle. Making my own would be much less expensive. It is sprayed inside the coop when I clean it to discourage mites, fleas, bugs, etc.
Pumpkin seeds are a natural de-wormer for chickens and I had one small pumpkin still rolling around the yard from last fall. I cut it open and ground up the guts and seeds in the food processor and fed to the chickens.
