I'm going to be getting 3-4 pullets in a few weeks so I want to get started on the coop but I'm completely overwhelmed. I'm in cold Massachusetts and have almost an acre. I was wondering if I could do a smallish coop in a tractor for moving around during the summer and a separate, larger cold weather coop next to the house for during the winter. Is this hairbrained? Should I just do one tractor coop and then plastic/weatherproof it as well as possible come winter? I have an old doghouse (nice one, with windows) that's maybe 4x4 feet. If I built it out a little and put the nesting boxes jutting out the back, could this work with a big run for the summer? If so, I could just focus on the winter coop. I have two little kids, so I don't have a ton of time, I'd rather do it right the first time. And, finally, are there any plans you'd recommend? My FIL is quite the carpenter, so I'm going to enlist his help but he'd like very detailed plans.
