Hello, I am another new guy to BYC. My chicken run is about 15 feet by 20 feet. I currently have 6 chickens that have turned that area into bare ground (when it is not covered in snow). I can't let them run loose anymore because of the hawks (which killed 3 chickens last summer), so is it ok for my chickens to ALWAYS be in that area? They really love to roam the yard, but I have to protect them. Also, I always see pictures of chicken runs that appear to have plenty of chickens and still have nice lush green grass. How does this happen. Thanks for reading.
