Can someone please enlighten me as to what a pencil test is when it comes to trying to sex a baby chick? I was on the Homesteading Today forum and someone said (and gave the link) they saw a person trying to sell something on a well known auction site that swore it would tell what the sex of your chickens were. Everyone in the forum stated that it was the "ol pencil test". I guess I'm ignorant because I have no clue what that test is. Just curious and thanks.
