I am new to chickens and have a question about coops. I intend to have a large flock of about 25-30 laying hens, plus a few roosters. I've done my research and know that, as a rule of thumb, 2-3 sq ft per LF chicken is ideal to prevent problems arising. What I want to know is: Does this number hold true even if they have a large run? I'm trying to explain to the checkbook holder why a 6x8 ft coop would not be large enough. She doesn't want to listen to me and insists that she knows what I need.
