Stony, as a new discoverer of just how many breeds of chickens there are, & having a curious nature, I'd like to ask (about having to go outside - do you feel this would apply to all breeds (assuming they aren't some tropical thing) and situations? I ask because I wonder if the game bird types like the Sumatras (am I correct in thinking they are more like a wild type (closer to pheasant, partridge etc than some breeds?)) would maybe be more suited to this lifestyle? Just to be clear, I'm asking from a learning point of view, not being argumentative.
For your consideration, here close to the lake we get high winds, like you mentioned you have had, but also tons of snow, as you may be aware... at our house we are square in the lake effect almost every time; it is not a surprise to have 2-3 or more feet of snow in a day or night, pretty much run of the mill. Sometimes days in a row of it. Several years ago we 13 feet in one weekend - which is unusual lol.
We are rural, so the flock will be free range at all times i.e. the pop door open during the day no matter the weather, no run, but we don't really have any perching type trees, branches on the hardwood are too high. I imagine they could use the Spruces, but so far the BCM (the only ones outside yet) don't seem inclined to even go near them...
Anyone I'm happy to hear your experience and thoughts or questions to join in the discussion too, I just directed it at Stony as he mentions his experience, so I figure he may have some thoughts for me to digest.
