Thanks for asking, "fuzzi"!
Well, I decided for my current issue and for future use when adding new poults or if isolation is needed, etc. to order a small coop with a small contained run for ~6 chickens ... which should actually work for two, if you know catch my drift on how they over-estimate the bird capacity.
I made this choice because the "be-atchy bird" tension in the evening has ramped up against my ~15 wk old Blue Wyandotte and her sister newbie Buff-Orpington with my three established older R.I. Reds. My three Easter-Eggers/"mutt" Americanas haven't had a problem with the new girls, but the Reds are a different story! So, I'm going to go through the whole pre- waterproofing and then assembly process with a kit again, as lame as I know that sounds, in the interest of expediency.
One of the factors in that decision is that I live only ~25 miles inland of the Gulf of Mexico, and know well that a hurricane is possible every year. If need be I can relocate both my existing coop and a new small coop under a patio area in my backyard that has a solid roof over it and three stone walls. It will be a very tight fit, but they'll be as protected as possible and they'll still have fresh air and light, as opposed to trying to drag their homes into my barn.
That said, my go-forward plan is to still build the hoop coop, because I love the idea that they are light-weight and therefore nearly as moveable as a "coop tractor" setup, maybe even more so, and largely because I think it would be a great dual-use base for a greenhouse set-up to both shade my vegetables from the wicked Texas sun in the summer and as a seedling greenhouse in the winter, with just some cover material changes from landscaping fabric to plastic and also work for chickens. The downside, if used for the chickens, is that it would be gone in short order in a hurricane. Dead plants I can deal with .... "The Girls" are a completely different story. ; -}
So, if you have any tips or pieces of advice to give me on your hoop-coop build I'd love to hear them!
Thanks so much, Fuzzi!
