love the coops made from repurposed materials. this is a nice job!
I do think if it was me, I'd add more ventilation though, those vents are small. Is that a gap at the top of the wall on the human door side? that will definitely help if it is. Think along the lines of 1 sq ft of ventilation per chicken, so you can measure what you have and apply toward how many chickens you have
Here are 3 of the four vents. I am planning on adding a small slider window with a screen above the nest box to the right of the vent. If one would ever show up on Craigslist...uggh. I priced them at Lowe's...way outta my budget, lol.
Believe it or not for being a smaller hen, Sunny here is the queen of the coop. She is also my Easter egger. Love me some green eggs and ham. (My 3 year old daughter named her.)
