When I was a kid, between the neighbours and an uncle that butchered chickens, I learned to toughen up and even helped with the process since I was 6 . However when it was my own birds, it was a little rough at first. I knew these birds from chicks after all. A few I was happy to dispatch, like the mean roos! But, there were a couple of fellows that were a bit deformed. A crooked beak on one and crooked toes on another. Being one that goes for the underdog I wanted to keep them, but I knew that they would not be best choices for the good of the flock. Some were very pretty, but of no other value. I finally had the husband of my son's friend come and do the deed for his pick of 3 that had to go. I will admit, I did give a last minute pardon to 2 of them.... sometimes you just get a 'feeling' that they were meant for something better. One is now living on a VERY nice farm and is the proud daddy of his first 8 chicks. The people I gave him to just love him and say he's even good with the kids! The other I still have. Maybe he's meant to take his daddy's place, we'll see. Anyway, yes, it can be hard. But yes, you and your kids can get over it. It's something people have had to deal with since man started domesticating animals. ALL LIFE FEEDS OFF OF DEATH. Even plants. BTW.... I know this will rub some people the wrong way but.... I am Pagan. Before I take a life for food I thank and bless it. I served it's purpose in the circle of life, I feel it should have that respect.
