I looked up the Muncie Ordinances and it's a little confusing.
First, it states anyone living in an area zoned R-1 thru R-6 are prohibited from keeping poultry but then in the next ordinance states as follows:
Sec. 90.21. Fowl running at large.
The running at large within the city of chickens
and other fowl is unlawful and is prohibited. It
shall be the duty of each and every owner or
custodian of any chicken or other fowl within the
city to confine the same upon his premises.
(Ord. No. 16-03, § 21, 8-4-03)
You can google Muncie Indiana City Ordinances and go to your cities home page. There you will find a link to download city ordinances. It is under section IX-3 Hope this helps.
I thought it was contradictory so I would call and ask for clarification.
