Well, to be fair I did not do the math on the size because I was looking at it way too late at night. I was not surprised to see that the Amazon coops were a fail, it is sad, but they can't be real wood and are all really small. I feel like we will wind up building our own, or looking for a small shed to convert. The problem with those is that they running so high right now that people want to put their mowers in them. I thought it was worth a look. We can't do a tractor because the property has such a significant slant and putting 11 in a tractor would make it a size that is sooo heavy. Thanks for your feedback. We have always built, and guess we will again.
Not to knock Amazon. I've made a lot of purchases from them. For the most part, I'm happy with the quality of the products. Amazon does not make the coops, as with all their merchandise they go through independent vendors, many of them are small businesses. The coop I purchased was wood, however they are being manufactured by people who know little or nothing about raising chickens. Building from scratch is a much more cost effective way, just make sure you design it to work for the long term. Good luck!
