Cook County, Il trying to get rid of my "pets"

[JMJ62]

I've had chickens for 3 years and now, through a grumpy old neighbor, the county is telling me they are pets and since I have 2 dogs I can only have 1 chicken. Anyone had this problem> I know my neighbors have cvhickens but I'm not going to turn them in.

What are your county's, town's and neighborhood laws regarding chickens or poultry?
