Loving the replies on here, thank you all. A lot of my concerns have been brought up here, and I'm so glad to hear (err, read) that I am not alone in my concerns.
Selling off my bad roosters seems like a terrible idea to me for a lot of the reasons some of you have mentioned. When I have my good quality stock for sale in the future, I do not want anyone to be able to say "Well, she sold me some crap birds 6 months ago." Telling people something is pet quality and NOT true to standard is one thing, having them actually grasp the meaning of that is another.
I think I am going to eat my roosters, sorry boys. Hens I could never eat though, so they go in my personal flock for eggs or sold to someone I know can understand the meaning of pet quality. Of course not everyone is going to want to breed, a lot of people just want some hens. My main concern is when raising a rare or highly desired breed, any culls I sell may end up being bred and sold due to their value, even if the birds are not true to the breed. Such as with Marans, they are the "it" breed right now and any culls I might have with my wheatens, I would not want to sell them in case they are being used to breed. What if someone cannot find a good quality roo so they buy a PQ roo and breed their decent hens to him? I worry about this kind of thing. It was a lot easier when I just had a mixed flock running around lol.
Thanks so much for everyones replies.
