Hi all! Need help with how to safely introduce new ladies to my backyard 'flock' (of 1) We had three 3 pullets (Cochin, Easter Egger, and Orpington) that we brought home. They were good for a couple/few months. We now have only the Orpington left. Cochin went first....then Easter Egger a couple months later. I won't go into the details, but am nearly certain it was Marek's disease. It's been another few months and the Orpington is doing just fine. Looking in to getting a few more pullets (vaccinated) to keep our lady company and looking for suggestions on how best to clean up the chicken yard, etc... in hopes of preventing another outbreak Thanks in advance for your help!
