I had a Johnny house for years. I really enjoyed my quail. I had one of the best training quail I've ever seen. I named him Rocket. He would fly out when the top door was opened and find a great bush. He'd flush if the dogs got too close. A couple of flushes and he would fly right back to the Johnny house and into the funnel. Rocket got sick and died. I buried him.
The quail can become flight conditioned by jumping up to the ledge in your Johnny house. I gave mine away several years ago. Here's a picture for you.
Quail hunting is like walking into, and out of a beautiful painting all day long. Gene Hill
