These plans are in no way renditions of cheap prefab coops. Honestly, I think your comment was a bit harsh,
Not in fabrication/materials, but in size/design. It was harsh, but it was honest.
Didn't see a
coop this large, unless it was including the run-which doesn't count and is misleading.
The '4' is a saving grace, kinda, but folks won't look at that they'll look at your max which is near CAFO tight.
They were actually designed by a professional architect who used my own hand-drawings/designs
Yes, wonderfully modeled, rendered, sectioned, detailed, and animated(I used to do this for a living) but to
your sizes, shapes, and configurations.
Common 'rule of thumb' currently around here is 4sqft per bird in coop and 10sqft per bird in run MINIMUM...and that will not facilitate integrating new birds or isolating sick/problem birds, which is a very common need. Sorry you feel picked on but we see
tons of problems due to over crowding in tiny coops misrepresented by manufacturers or plan sellers, we are passionate about the birds well being and the keepers peace of mind in providing their charges with good housing. If you had researched space needed here you would have learned that stuff.
Good ventilation is difficult in small coops, another reason they are not particularly functional. Sliding windows are not practical as they let weather in(rain/snow) and are just about worthless as ventilation in cold climates during the winter because of drafts directly on birds at roost. One thing you have going for your designs, at least they have roof overhangs which are good for tucking ventilation under the eaves but I didn't see anything about venting in the illustrations.
