Hmmm. Theres a lot of beef being bought online these days. Don't know about chicken because it's so much cheaper, usually. But maybe you are looking to put up a directory site for local poultry sellers. Just depends on what your aim is.
Btw, "selling poultry" is more common then "dealing". So maybe keep it in mind. "Dealing" is traditionally for certain niches like cars etc. But if you think you can go outside the box, best of luck.
