I completely agree with responsible breeding/ownership of all animals and know where you are coming from with your original post. I eat meat from the grocery store, which admittedly has a lot of bad stuff in it and I have been switching over to organic. I also understand that many, many people raise and process and consume their own meat, and I also have absolutely no problem with that. Or hunting for that matter. In fact, I've eaten meat from a hunt and meat processed by a family who raised beef for that purpose.
However, for me, I cannot raise something, care for it, and then kill it and eat it. I don't know why, I just don't have it in me to do that. I wasn't raised in a family that did that, so I'm sure that has something to do with it.
I recently rehomed a rooster and a hen because they turned out to be a different breed than what they were advertised as and the rooster was turning out to be very aggressive and unpleasant. I wasn't asking for a "pet home" for them. I felt that once they were rehomed, if they were part of a farm, backyard flock, petting zoo, or dinner table, wasn't up to me once I let them go. I hope that doesn't seem irresponsible or heartless. However, may seem like the easy way out for sure. I don't know what I could have done differently with them, I know I couldn't kill them and cook them for dinner.
As far as acquiring new chickens for my flock, I don't take a chance on sex. I know I want 1 rooster and the rest hens. I don't buy unsexed chicks or hatching eggs. I do my best to not get another rooster. That said, I have an extra rooster right now. Was supposed to be a pullet, and I'm quite certain he is a rooster. The breeder is letting me exchange it for pullet. It was a case of a bad guess on sex by the breeder.
Just wanted to add another perspective to the discussion.
