I had a guy last night call and want to bring a bird back that turned out to be a rooster. He did not want it to go to someone that would eat it.
I told him he could bring it back, but I would just wring it's neck and throw it in the garbage. He wanted to buy another. I was honest and said I can't bring hm back into my flock once he leaves.
I just don't tell them what I am going to do with them but I do not return birds to my flock after they have lived somewhere else.
