I have something similar but 36x32, I call it the chicken yard. We just built it at the beginning of spring but I planted a rose bush, fig tree, apricot tree, and a crape murtle. They don't mess with the crape myrtle at all, but I have 1"chicken wire around the rest. I did some seeding in the grass for more variety and nourishment. I can't wait to see your finished project! You've got some great responses and opinions!So I am planning to make two secondary day time runs, each about 12 x 18 x 6 tall... I will only allow the chicken access after the plants have grown to a stage that can handle the birds...
