I brought my chickens home and that was it. No process needed.
Going to order a few more fluffy butts this week as the place I get them from finally has its dates from the hatchery. The first day of the first session last year saw over 5,000 fluffy little ones go through the doors.
I also didn't need a permit to build a coop.
Make certain you dot your i s and cross your t s or the application police will haul you off to jail.
