I have a 112sqft coop with a 200 sqft run and about 2/3rds of an acre. If chickens should have 4sqft per chicken, then I can have 28 chickens. But I have enough room to have perches that are 8ftx6.5ft and with each chicken having a sqft on the perch, I can have 46 chickens. So I'm wondering how I decide to know how many chickens I can have? They will be outside during the day, then have their run locked up which has a small opening to their coop. I live in WA so it gets dark at around 5-6p.m in the winter time. On average in the winter time here it's 40 degrees. If I can have 46 chickens, how many roosters can I have with them?
