lol I've had that happen, when my quail were smaller I built a lil structure with cardboard it had no bottom so they can eat grass, bugs and dust bathe, and no top, cause everything said they couldn't fly well, but last time I had taken them out they were 4 weeks old then I was bust all week so I didn't get to take them out again till they were 5 weeks old so they did their thing and I sat in a chair next to them, then my only golden flys away like 20ft I just laugh and go try to catch him. Then he flys all the way to my front yard in the brush so while he was flying I was running behind him with flip flops on. Well I never found him. But the next day he was hanging around under my deck but my cat never gave me a shot at catching him she chased him away then that evening it hailed pretty heavily and I never heard or saw of him again. I guess they just go back to familiar terrain where they know theirs food, water, and other birds just like them.
