Livestock manure like chicken and sheep waste can be harmful to the environment and health. Black soldier flies can help by converting this waste effectively. A study looked at how well black soldier flies reproduce and grow when fed chicken or sheep manure. They found that flies raised on chicken feed grew the fastest and had the most offspring. Flies raised on sheep manure took longer to develop. Overall, chicken and sheep manure are good for black soldier flies, but they reproduce less compared to being fed chicken feed.
