I do utility work in West Chicago and I can tell you there are quite a few houses with chickens especially around Pioneer School and around the Jewel. Perhaps asking Scott at Bob's Salt and Feed would allow you to post a flyer on the bulletin board.
And yes I'm going to go to bobs salt and feed and trellis in st Charles and post flyer! I emailed a guy at the city hall in st Charles asking how the zoning was modified in their area. The city counsel meeting is August 4th Monday which is our deadline when were suppose to get rid of our chickens I need as many people to come down there if we want this change
