You might be surprised. Most of the breeders i wind up in conversations with are more likely to be irritated that people are still using their good name to sell birds that haven't been in their control for years. Mentioning where your original stock came from and how long ago is of course appropriate and helps puts the background in context, but still selling chicks as "[breeder name] line" ten years after you bought birds from them is generally not much appreciated. People can ruin a line with a single season of breeding even good birds, and nobody really wants to be associated with someone else's potentially awful breeding decisions.
