My children used to insist on bringing along food and water for the chickens when we went to do kapporos. Then they refused to go. I have seen children chase and abuse kittens and dogs, my daughter once saved a kitten from being attacked by a crowd of boys.
My husband just does it for us with money. The only way I could do it is if I raise my own chickens and bring them to the shochet. Just chickens are so noisy and MESSY.
