Hi, I'm a relative newbie to raising backyard chickens as I've only had two at a time. I currently only have one Red Star (and have only ever had red stars) and she needs a buddy or two. My options are to get a pair of Red Stars or Silkie or Speckled Sussex. What would you all advise would be the best breed to add to my sweet hen. And is it best to get a pair or add one at a time? Thank you!
