My Buff Orpington is pretty easy going, has little flying ability and seems to tolerate temperature extremes -- it's hot and humid in northern Iowa in the summer and bitterly cold, dry and windy here in the winter.
Her coop mates are Salmon Faverolles who are the most docile birds I've ever known. I bought them when they were just a few days old and handled them daily. They can barely fly off their high roost and have the most amusing gait when they run. This will be their first winter, but they are very fluffy and are housed in a study coop, so I'm not anticipating any problems.
Honey, Celeste and Camille all free range during the day, but will race each other to get to the back door -- where they sometimes peck at the glass -- to persuade their people to come out with grapes.
The rest of my flocks include Iowa Blues, Sapphire Gems, Blue Laced Red Wyandotte and Cochin Bantams. The Wyandotte and Cochins are "catchable" and not great flyers, but not nearly as easy to work with as Honey and the Favs.
