We live on the Oregon coast and today we brought home 5 chicken. My husband built the Taj Mahal. Sp? Of chicken coops and we did a lot of research, (on here and other chicken owners). We brought home 4 hens and 1 rooster, all of them Buff Orpingtons. They are resting comfortably and all huddled together on their perch, the rooster in the middle. We are excited. I keep hearing tho about Marine disease. What is that?
