We have 22 chickens. They have a very nice, roomy chicken coop (which is actually big enough to be a child's playhouse) and a very large, fenced in chicken yard. They have sun and shade and water in the yard .. and for a chicken, it probably pretty pleasant. If chickens ever thought anything like that.
Some of them have figured out that they can fly and perch on top of the gate to their yard .. and thence to freedom in our one acre property. Some of them haven't figured out the flying bit yet and so remain "ladies in bondage". :-)
One of my neighbors adores the chickens. She lives in a condo with just a pocket front and back yard. She loves to bring her kitchen produce scraps over for the ladies to eat. The latest offering was a head of leafy lettuce. I cross-cut the head of lettuce up so it would be in long strips.
