Hi! That's exciting you are getting back into chickens! I would suggest getting more than one Polish or other larger crested breed since they can often be a target for being bullied by the ones who don't have such an awesome hair-do. I think if you get more than one, there is a greater possibility they won't get singled-out. Plus, who can resist a Houdan or Appenzeller Spitzhauben? (Not sure if those are available to you, just for suggestion.)
Thanks for joining and welcome to BackYard Chickens!
