I am moving back to Fort Wayne and wanted to know if I could have chickens so I checked http://www.allencounty.us/dps/ where I entered my address and clicked Get Zoning Status to find my zoning status (RS-1 means you can have chickens). Yes, it appeared I could. To be sure, I called them at 260.449.7607 and the very nice and helpful people confirmed that my address is, in fact, allowed to have chickens. I recommend you do the same.
I called the city , I think it was and they said " anything considered livestock is not permitted. I said not even a couple only? No.
