Lots of nice chickens out there that make good pets. But as Drumstick Diva has mentioned, it is always better to get two of them. They are highly social creatures and really need the companionship of another bird. You can still make nice pets out of both of them. Good luck and enjoy your new adventures!
Good luck with your poultry raising adventures, and I hope you find everything you need to know. Don't forget to take a look at BYC's very useful learning center (If you haven't already)! The learning center as well as the forum should answer your questions! Glad to have you here! See you around with the flock. Buff Orpingtons are cute and friendly.
