Hubby and I spent waaaaaaaay to long building an A frame coop that is very cute but a total PITA and I hate it! I seriously wish I'd pushed him to forget about it when we were half way through and just build a walk in - easier to clean, easier to access your birds when you need to go in after dark to deal with injuries or ilness, space to add a broody box etc etc etc! The plan was for us to get the 'big' coop done before this winter but of course our own house building has taken priority adn I have too many chickens in the A frame. Ah well we live and learn. I LOVE your shed it is so so so cute - I think many a chicken owner would give a back tooth to have a base like that to build on! Particularly with your weather I'd nto see a better solution! Good luck and let us know how you go.
