so http://www.clarkfarmbusiness.com/Chicken-Coops.html these people seem very knowledgeable but 1.6 sq feet seems small. my stepdad now thinks that us giveing around 3.5-4 feet per bird is way too much space. i told him that we still should build a 6 by8 for 10-13 chickens but now he wants to do something like 4by 8 which is only enough for 8 birds. wouldnt they fight? we were thinking about designing off the salt box coop that they have. what do you think? P.S. if this should be in the coop design/con. please move. i wasn't sure because it is sort of a mix. eta i also have a run that would be attached and there also would be in a pen and can free range from 2:20 to night most days.
