Hi Everyone: I have some questions I really need help with. My husband and I are considering a move to Philadelphia from Northern California. I have, now, seven hens. They live in a large fenced in portion of my "mini" orchard. It is netted top, side and bottom with the red light deterrents. Lots of trees and shrubs. There are two coops within the yard--one small and one large. They usually sleep in the trees but the coops are there for heavy rain and eggs. I've never had to deal with extremely hot or freezing cold weather. So, what do you do about all that? How do you keep the chickens cooler or manage extreme heat. Also, how do you keep them from freezing to death? I know many of you, if not more than 2/3 live in parts of the country where these elements are an issue? Thanks for your help.
