Aaron cut some 2x4's and placed them in the spaces of the fence to create the corner roosts yesterday. I went out a while after letting them out of the coop this morning and 2 were sitting on it. They also like to hop on the run and coop to roost. I even caught them on the compost bin this morning. I am hoping once they have a nice large graduated roost set up they won't bother going on the coop and run.
Although, they will really roost on anything that happens to be lying around, regardless of its purpose. Here is a bucket I had put a cooler in to create a cool area for the chickens to sit in. I should really have taken it out the same night.
Gotta love that face!
