Like Cedar stated you might look into ducks or Turkeys as well. They don't lay as well as a chickens, but your daughter might not be allergic to them.
On the subject of scraps and feeding. I fed 70 chickens through the winter on a diet of anything the grocery stores toss. If you have enough scrap from your source you can use it to replace all of your birds diet, and they will be healthier. Chicken feed is bottom of the barrel. While there are problems with our food supply it is better than chicken feed. Your birds diet will be much more diverse and you will get better healthier meat and eggs.
I don't have a compost area, I just put the scraps on the garden and my chickens process it and redeposit it in the garden. Compost piles are for people without chickens.
I have not tested this with quail yet, But chickens, Turkeys and Muscovy ducks can easily be raised on scraps. I see no reason why it cannot be done with quail, and is worth a try.
A picture of my chickens diet this winter consisting of chopped apples, corn on the cob, lettuce, bananas, pears, squash, cantaloupe, water melon, pineapple, tomatoes, green beans, cereal, bread and 100's of other good eatings with guacamole toping all for free. They ate better than 90% of Americans.
