Indeed. And get a good mentor! When one is fully antiquated with a breed they can look at their flock running around and be able to pick out breeders and culls.Form's relation to function, and vice versa, varies from breed to breed like it would in horses. To get it, is to get to know a breed and know why it should be what it is.
Just the other week I had some one contact me for a Light Sussex cock I asked where they got their stock from they had U of Alberta strain pullets (think leghorn size). Once they got here I was able to pick out a cock for them in about three minutes. I knew what would pair good, because I have seen a pairing like that. It also came with an intimate knowledge of the breed.
Ohh gjensen don't worry I get you completely - I am also bad at explaining.
