I am a very new member who is so excited to start out. I won't get my chicks until the end of March. Eggs are really a secondary reason for me to have chickens. My most close-to-my-heart reason is to have a good experience with the chickens for both me and my grand kids. I only want to have four hens. No crowing please, remember the neighbors! I am debating between all buff opringtons or a mixture of buffs and austerlops. Any advice?
