Sell them! Advertise them as being of good temperament and sell them! Many folks out there looking for a well mannered roo that's a good flock master. I know if I could find a good, young rooster in a breed I like and it had the right look and temperament, I'd pay up to $15 for one.
I am going to advertise them for sale first... have sold 2 and the folks loved them. I won't sell a rooster that wasn't a good flock and people bird.
