1. Build a good, solid coop and run. Draft free...no leaks (our mistake).
2. Research the breed. If you need a winter hardy chicken, don't get a Sebright bantam. If you have kids, research which breeds are gentle. If you are wanting eggs, research which breeds are good egg layers, etc. etc. THIS WAS OUR BIGGEST MISTAKE! My boys chose a breed that was "pretty". I had no idea there were so many different types and temperaments.
