I have 6 chickens. 3 are 17 weeks old, 1 is 14 weeks old and the other 2 are 11 weeks old. The coop I have is 5x2 and the run will be 6x6 ( I'm still working on that). Is this big enough for my 6 chickens? They also get to run the yard when I am outside in the am and pm. Probably about an average of 1-2 hours a day.
