Very informative thank you. I have a compost and chicken farm in north east Thailand. We also farm worms and Black Soldier Fly. We have a good biochar production facility also using specialist kilns with gasifiers and wood vinegar and bio-oil capture. We use biochar powder in our chicken houses putting down a layer on the floor first then we add more once every month and it is gently raked in to the woodchip deep litter bedding. Our birds aren't so dense as a larger commercial house, we have around 4.5 birds per sqm only. Our chicken houses are open sided above the perimeter nesting boxes with wire mesh only to aid airflow. Our primary reason for adding biochar to the bedding was to produce a better quality compost product from the bedding but we do believe the hens prefer it too as they do eat some of the biochar and they are more inclined to scratch around looking for biochar thus helping to aerate the bedding. We also make our own chicken feed mix made into feed pellets using our machines and the feed pellets include a small amount of biochar powder added together with the other ingredients (Azolla, BSFL, Cornmeal that we grind ourselves, a little salt and traces of a few other ingredients). Our feed costs are about a quarter of usual commercial farms so we run far greater profit margins on our egg production (our cost per hen per day is about 1/2 baht compared to the usual 2 baht per day per hen here). We of course use biochar in our compost business too. We add raw biochar when we create our aerated compost piles and we also produce inoculated biochar for direct sale. We are also selling raw biochar to other farmers to use specifically for their chicken house bedding or as a feed additive. Our biochar is produced using old dry wood, bamboo and coconut shells predominantly and our kiln baking temperature runs between 600-900 degrees Celsius.
