Moving into a new home in Golden, CO. We are turning a large divided dog house/shed with completely enclosed run into a chicken coop. I am looking to get about 12-16 chickens, these will be my first. I prefer brown eggs. I am defiantly getting Barred Plymouth Rocks for their personality and egg production and I'm pretty sure we'll do the Rhode Island Reds for the production (I understand they can be a bit bossier than the rocks). My question - I'm not sure which to add to these guys, either Buff Orpingtons or Buff Plymouth Rocks. I can't seem to find much information on Buff Rocks, can find a ton of info on the Barred Rocks. Any thoughts/advice from more experienced chicken folk is greatly appreciated regarding which of the Buffs to get?
