Hi! I would like to suggest Craig's List/ Denver to find a rental that is chicken friendly..... You also want to be sure the city/county you live in is chicken friendly.
Plan on making your pen/coop safe from foxes, coyotes, skunks, racoons. We have plenty of them and they can cause havoc with a flock of chickens. Mine run in the yard during the afternoon but they are behind a fence with a screen covering at night.
Good luck with your venture! We have loved having our chickens.
Thank you Sandy2370, I will definitely look on Craig list and make sure my coop is safe for my future chickens. Yes, I have been looking at the different towns and rules.
