Welcome from a fellow Utahn! Watch out it's addictive...but they are so much fun! I just picked my 13 baby chicks today that is a total of 37 hens for me and 1 rooster, OH BOY!
Your chickens will love the orchard and garden. We fence our garden with two foot high chicken wire, keeps 'em out, but would not keep them in if that was around their run.
