Breed profile
Buff Orpington
The gentle giant of the backyard. Orpingtons came over from England in the late 1800s and became one of the classic American farm fowls; the buff variety is still the one most families meet first, and the hatchery page calls them a perfect family bird. Hens run 8 pounds, roosters 10, with the heavy full plumage that makes them excellent winter layers, shelling brown eggs through cold weather when lighter breeds back off. Two things to plan around: that mass asks for shade and constant water through a heat wave, and the first egg shows up at 5 to 7 months, later than the production breeds.

What this means for your setup
Size everything one notch up. Eight-pound hens want the generous end of the coop-size calculator, roost lumber sized for big birds, and a pop door that fits them. Broodiness is a feature to plan around: Orpingtons are excellent setters and mothers, which pauses the eggs but hatches the next generation for free. If your plan is eggs, not chicks, a way to break up a sitting hen (or a spare nest to isolate her) belongs on the shopping list next to the feeder and waterer.
