Quote:My exhibition line langshan and barred rocks would likely find 12x12x12 too small. My feedstore (hatchery) orpington, barred rocks, rir etc. would be fine. My feed store brahmas would find them too small. Build for the size of your birds. Since you have a few inchs to play with consider making one or two that are larger/smaller than the other. That's a pretty good idea. I'll divy up the 48" into small, medium & large.
