I just gave away most of my 6 week old Bob-white babies. I kept 2. One didnt make it through his first night outside, even though he had all his feathers, a friend, and a heater

.
Now I just have Dale. As Dale matures, I've noticed that Dale might be a girl. So...whoops..haha. I kept Dale because she is an escape artist and an excellent hider. She organized alllll the escapes when all her friends were around. Boy, was that hilarious every time. I couldn't give her away because 1. She would have given the kind farmer who took them all in a hard time and 2. She escaped when I was boxing them up...and then hid! She has a cute little house and a heat pad that heats up to around 70° for these very cold "summer" nights we have been having.
My questions:
1. How do I get her to not be afraid of me? I spoil her, so buying her love is obviously not working..
2. Should I get her some friends? Is she going to be lonely?
3. Should I let her out of her cage sometimes? If I do, will she come back?/How do I get her to come back? There are hawks, raccoons, and feral cats around at night...A super adorable kitty was stalking her last night when I went to check on her. So next time I visit her at night I'm bringing cat food
4. When might she start laying eggs?
As you can tell, this is my first time raising quail. I've hatched eggs (chickens, ducks, quail) every year with my first graders, in Chicago. This year was the best hatch rate, and the first year with quail. 3 chicks died the first week (so sad :'( ). But the other 7 were really funny and so interesting to watch interact with each other.
