Your tractor coop looks great and obviously it's serving it's functional purpose. I especially love the poop drawer/pull out - I will want one of those two.
I am taking on the task of building my own coop too. My SO was very helpful in buying the lumber so I am very grateful for that, but he isn't actually helpful in building it. Actually he criticizes me so much it upsets me. And it isn't about how 'perfect' my framing is, because actually I have it very perfect. It other things like how I hold the nail and if I'm wearing gloves. So, though I love him dearly and he would build the whole thing for me if I asked - instead i prefer to work on it alone and get the sense of accomplishment myself. It seems peaceful to me to be in the work shed build the coop and knowing that my chickens are going to be safe in what I build for them.
So I give you KUDOs on the work you have done!!!! and all the other folks out there building their beloved chickens and nice 'house'.
