One of the two bantam cochins I got from a 4-H girl is a frizzle, which I initially refused (I REALLY wanted her blue-laced red Wyandotte). The frizzle free-ranged during the day with and slept at night with full-sized chickens. I agreed to take the barred bantam cochin so the BLRW wouldn't be lonely with no friends from her previous flock, but I worried that northern Iowa's frigid and windy winters would be too harsh for the frizzle. Anna rightly pointed out that the little one had done fine in an unheated coop and free-ranging with the others the previous winter. And, the little red would be the only bantam left in her flock.
And, that's not only a story about how frizzles aren't necessarily as delicate as I was led to believe but also shows how chicken math works. All I wanted was the Wyandotte.
