Polycarbonate shed retrofit for coop

[My Very First 6 Chickens]

Can I get your opinion on this design's ventilation? This model still has a way to go but I'm using it so I don't make these mistakes in the large scale (model is exactly 1:8th scale of all of the materials I plan on using or have on hand, the standee is exactly my height in 1:8th scale as well- 5'5")

It might be hard to tell and I plan on putting this together more tonight but instead of a solid wall, I step the roof tiles out a bit so it is capable of catching a bit of air and keeping the drafts above their heads. There's going to be a wire floor and open front in the summer to keep it more of an open air concept with a removable front wall for winter.

Your adorable and clearly SO excited! Good luck! I have had chickens for over a year and I cant imagine life without them
