I tend to agree with you when it comes to wanting a bird with some "spunk". I have had a variety of hens as part of a "yard bird" band (I imagine most of us have had such a thing at one time or another). Ones that I didn't intend on breeding, but I needed eggs for breakfast and didn't want to eat the eggs of my show cochins. I always seemed to be drawn to the active hens. My favorites have been a Fayoumi, Welsummer and a La Fleche. All of them were good foragers and active. Of course, I only had one or two of each, so maybe I was drawn to those particular hens and they were not indicative of the breed. On the flip side, though, I had a Lakenvelder that was just plain crazy. There is such a thing as too fiesty as well.I played around for years, and began to have a preference for a type. That type was best represented by the New Hampshire. The New Hampshire could be said to be my "first love".
Overtime I came to appreciate more active breeds, that to me, made better old fashioned farm breeds. I prefer the colors black tailed red, white, and buff.
I began to wonder why there was no dual purpose birds that had the Mediterranean style, and in particular a Spanish flair. I sought out some Catalanas, and have made them my "project".
I like a bird that has some "spunk". Personality. To me, calm often meant lethargic or lazy. I like a bird that gets out and goes about it's business. I also expect them to fill the egg basket with large and extra large eggs of good quality.
I think choosing the breed is choosing what interests you the most. I think it is that simple, but not always so simple to know.
