HI! I'm a Berks Countian as well!Hi all!! I'm a newbie with two newly adopted twelve week old GLW hens. I adopted them from my brother-and sister-in-law. She has been giving me a lot of advice on raising chickens and she referred me here. I live in Berks County, PA. Any advice for my area? How will they winter? Should I provide a heat source or will they be ok without one? These are my first chickens ever and I'm going to see how things go with them before getting anymore, so it's just the two girls to keep each other warm... Are there any ailments that GLWs are susceptible to? I'd appreciate any advice so I can do right by my girls
