I am looking to expand my chickens a little to create more of a sustainable system. I have owned a variety of chickens throughout the years and have come to the conclusion to settle on one breed. Now here is my take, and please correct me if I am wrong in my thinking. I want a single breed. This is so I can maintain the quality of birds, allow the hens to do the raising, and lessen the up keep. My thought process is that I create a system where I have a comfortable amount of hens that will provide eggs of course, allow a few to go broody every year, and raise a clutch. Out of the clutch I will cull the roosters and replace the unproductive hens. Then bring in a new lead rooster every 2 years to deter inbreeding as much as possible. First of all: am I correct in this thinking and system Secondly: if not, could someone give me a quick run through of what may be best.
