Thank you everyone for your replies.
To clear some things up. We live in southern California so our winters are mild and our summers are warm.
Everyone sort of confirmed what I already thought. the 200 budget was not really a total budget but what I was willing to pay for a pre built one vs when I thought I'd build my own.
With 8 hens I was thinking 4'x8' coop size with a run of about 16x8. We will free range when we are home and can watch them but when we are out at work we will have them in the pen.
Thanks everyone!
Go bigger, just a few more sheets of plywood... Make it twice as big, plan on it costing twice as much and taking twice as long to build. I spent a fortune on mine, no regrets
