Summarize this article in one sentence.
. For food you have a large range of choice. Suitable food includes: Game bird crumbles, finch/canary mix, turkey starter and some gravel or grit. You can also give them a wide range of treats which you can see in the steps below.  A common choice is to supply the feed in a feeder but if your quail live on dirt/grass you can try scattering the feed on the ground so that your quail can forage for the feed, they will love this. You could also put them on a layer pellets diet instead of their ordinary diet to ensure that you get the best eggs out of them. You can feed your quail many types of food including fruits, vegetables, seeds, small bugs, greenery and table scraps.  Quail can even eat meat if you want them to.  Quail are quite fussy when it comes to treats. But don’t worry, they’ll eat what they like and leave what they dislike so you will soon get to know what to feed them. Remember to dispose of foods that the quail do not eat instead of leaving them to waste away in the quails home. Make sure the water container isn't too deep or big for the quail and that it is in an easy to get to place. You should clean the container at least once a week to prevent a build-up of bacteria. Quail should not eat avocado, caffeine, alcohol, chocolate, salty or sugary treats, uncooked potato, tomato leaves and stems, parsley, citrus fruits and grape seeds as these all are toxic to quail.  Some types of plants are toxic to quail as well, so be aware of what plants you put in their habitat. Do not worry too much on what not to feed your quail as they will avoid toxic foods unless they are at the point of starving hungry.
