Now after all the laws are read... it was easy. We went downtown to the HEALTH DEPARTMENT, filled out the one sheet piece of paperwork. A health inspector called us a few days later. He asked if we had a chicken coop built yet and was it the proper size for the amount of chicken we wanted. We said yes. He made an appointment with us to come and see the coop. When he arrived he walk around the coop, asked us how many chickens we were going to have and said the smell would be the most important part... to keep it clean so no neighbors get upset. The next day the permit came in the mail. And there was NO COST for the permit. We just have to remember to call the Health Department to renew it in January of every year and state the amount of chickens we have. Oh almost forgot... NO roosters are allowed only hens.
