Agree 100%. There is a really good posting on the Jersey Giant board about when chickens go from being from a breeder and become your own. It is suggested that you give credit to the original breeder for giving you a start with stock, but after a few generations you have put your own interpretation on the breed. People inquire about certain breeding lines know for certain characteristics within the breed, but once it is yours and you start keeping and culling, it can no longer be considered the same as the original breeder's birds.No matter where you buy your birds you will have to work with them. Just go to the best breeder you can afford. You can't really go by the pictures shown.
As Rancher said, even chicks or eggs from a good breeder are likely to have some culls. That's my problem

From what I read online it seems that many find a mentor to help them make good choices to improve their flock. Tough to do when there is no one close who raises your breed and wants to take the time to help.
