I used to work at a quail farm. We kept hundreds of thousands of them in a big-ass barn, each room a different age cohort. We'd clean the rooms every day and collect eggs from the 8/9 week old rooms. Once a week we'd go into the 9 week old room with fishing nets, catch the quail, dump them into mesh bags, stick them in a bucket, and gas them. We froze them and shipped them to falconers all over as food and training treats for their raptors. It is possible to scoop up 109 quail in a moderately-sized fishing net.
