[Highland Park] local chicken suppliers?

Does anyone know where we can find a reliable supplier of chickens? Our normal supplier has run quite low recently and we need to be getting them on a regular basis for making cat food. We'd considered raising them ourselves but can't due to where we live, though we are willing to butcher them ourselves. If anyone knows of any farms in the area or folks who raise them and could pass along the information we (and the cats) would really appreciate it! Thanks, Heather
