Save my chickens

I live in Andover township and I'm trying to keep my emotional support chickens. The town ordinance says that in order to have poultry you need 6 acres. We are not raising our chickens for a food source we are raising them for support animals. I have a doctor's note saying that I need them for my PTSD they help to calm me and give me purpose but the town is telling me that there is nothing they can do to help me. The town is aware that other towns people have chickens but will not be violating any of them. My question is how is that fair especially when I need them for mental health reasons?? 

Thank you for all you help.
