I've had a lot of confusion with a chick I got from a bin labelled "commercial black pullet"... lol She has a dot on her head, like a sexlink, and the term "commercial" made a few people think "sexlink", which would of coure make my chick (and most of the other in that pullet bin) a MALE!
However, I was relieved to hear that these "Commercial Black pullets" are not sexlinks at all, but are an Australorp cross, that will turn out to be a lot like an Australorp (according to the hatchery that sent them to TSC).
