The list of suggestions could be quite lengthy,,, depending how many peeps respond,,, Many peeps will post their favorite chickens,, and they are all correct.
If you want pets,, like I myself keep,, and you are in Iowa,,, cold country. Look into keeping an assortment of Easter Eggers. They will provide you with colored eggs, and even if they are from same bin at sale place,,, they may produce different shades of egg color. (I had 3 from same bin, and each layed different color egg)
Are cold hardy,, and will live generally long life. Did I mention they are pretty

..
Avoid Sexlink chickens like Production reds,, Cinnamon Queens, and others like Isa Brown, Also avoid White leghorns. Those are great chickens if you are just in search for many eggs. They have short lifespans. White leghorns, are great, but not very friendly, and flighty.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
