The quail tractor is built. We built a little quail tractor to roll around the farm. It will mate up to a small "yard." We plan to use netting over hoops to create the yard. The idea is to raise the quail in a safe environment in a wire cage but also offer grass, dust and insects. The mix of safety and things that quail love ( dust and bugs) hopefully will yield delicious eggs. Tiny as they may bee quail eggs are reputed to be 3X healthier than chicken eggs. I can attest to them being tastier.
Side note: most quail are raised "on wire." this means they are always in cages and go not have the environment they were created for. Quail naturally live in woodlands and prairies. They take cover in the tall grasses, clean themselves with dust, and fly straight up and away at the first sign of danger. They do not domesticate easily like chickens. They must remain contains or they will fly away.
The quail tractor will function like a chicken tractor only it will have the "yard" function to keep them safe from hawks and contained. The tractor will allow for transporting them on the farm and keeping them safe from dogs and coons at night. Heres hoping it works.
