Oh wow that is a fantastic set up! And what a great idea for the salad bar. My set up is so much smaller so it wouldn't work quite this way but I do plan on doing something for them like this!
Your place looks like a "Chicken Habit Museum". Spic and span, all tidied up and ready to be opened to the public. What a beautiful set up you have, but I imagine in Alaska it is necessary to have such a chicken fortress. It is lovely though, and looks like an enjoyable place to spend the day.
Did anyone already ask, did you do all the work yourself? The sitting area is the best! Like everyone I am in awe of you!! More details, please.. We are all for making the world a better place for our chickens!
