Wonders why studs are 'sideways'.<scratcheshead>
Are you following a 'plan'?
Will roof be flat?
Welcome to BYC!@njchickenfam
Where in this world are you located?
Climate, and time of year, is almost always a factor.
Please add your general geographical location to your profile.
It's easy to do, and then it's always there!
Yes, I have a plan that I sketched up on graph paper, modified it a little as I started building. So some sketched, some in my head.
The studs are sideways because that's how some of the coops looked that I was trying to get ideas from. Also gives me some room to work with when attaching the hardware cloth.
