I was at the meeting as well, and I agree with what alicia2364 is saying. I still believe, however that for those that already have chickens, as long as they aren't reported they are probably safe. Then, even if they ARE reported, someone from zoning has to come out and issue the citation. Animal control only has the authority to enforce animal codes, not zoning issues. Not to say they won't try though.
There are several conflicting codes, and as stated before, the code prohibiting chickens specifically states that it is for the Residential Estates zone only. Like the vice mayor stated, this issue is becoming a larger one and gaining steam. The decision not to research this ordinance (or at least clarify and clean up the ordinances so there will be no confusion in the future,) most certainly WILL cost them more money in the future. In the mean time, my feathered friends aren't going anywhere. If I am ever to be reported, I will fight to the death to keep them. I would never advocate knowingly breaking an ordinance, but when we got our chickens I was told that they were legal. I'm not going to get rid of them.
