My DGD is the same way(she's 10), and I wouldn't lie to her about it. I want her to trust what I say all the time. What we did was let her pick out her two favorites that will be pets forever and the rest we'll eat when the time comes. She knows she won't have to watch the butchering or help with the cleaning but she can if she chooses. She won't have to eat them herself. But she does know that they are there to lay eggs for us to eat and to be eaten some day. I'm just glad she'll be 3 years older (give or take) when that time comes. Will she cry, probably. Will she be mad, for sure. Will she hate us for a while, definitely. It's okay. Animals are a wonderful way for kids to live and learn about life, especially that some of it is hard. In answer to my DGD's wonderful wit...no we won't eat grandma when she dies, but we will eat the chickens.
