I just thought I would post a link to a breeder I know that just set up a automatic feed system for his quail raising operation.
He raises 8,000 to 9,000 birds a year & he is also a professional bird dog trainer. Not only is it easier on him but he saves time & money buying feed in bulk and minumizes human contact with the birds.
If you are interested check it out at
