Love the run frame!
Will it have a solid roof?
Is the coop roof slanted to shed water away from run?
Kinda hard to tell from the pics.
Welcome to BYC!@ForkinAllotment
Where in this world are you located?
Guessing the UK (due to allotment reference?)
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!
