I have 5 chicks, they're 5 weeks old and tonight is their first night outside. They are in a chicken tractor, much like the design of the Catawba http://catawbacoops.com/ None of them have made it into the upstairs/roost portion on their own yet. Do they need to be taught to go to bed? I have shown them there is an upstairs, and they've played on the ramp... but haven't figured it out. They just lay down in the grass. If I pull up the ramp with them in there- with me manually putting them upstairs- do I need to include their food and water up there too, since they're young? Thanks in advance.
