So, this is my girls' coop. It has a small attached run and is inside an old 12x16 dog run. I am a first time chicken "mom" and this will be their first night outside. They are 4 and 5 weeks old. Do I just need to close them in the attached run or do I close them inside the coop itself? Their food and water is in the run, they would be separated from that I I closed them in the coop itself... Thanks in advance for your input!
