Looking for some advice on my coop. I have this playhouse that my son has outgrown... see link here for one very similar: http://cgi.ebay.com/Little-Tikes-Co...oryZ2574QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Anyway, I was wondering if this would be big enough for 4 hens, or should I keep it to 3? And when you talk about square footage per bird, does that include the run? We are planning to make this house be a tractor by putting some wheels on it, and will attach a fenced run to the front door. We were thinking the run would be maybe 4' x 2'. Anyone have any ideas about whether this will be big enough? We have a privacy fence that is 6' tall, so we will be letting them out for a couple hours each day. Will they be able to fly this high? Thanks in advance for your help!
