Chickens? but no eggs?

As there are no eggs in this eggless sponge but I still want to add our own chickens into the books giving some character into the recipe book. I would also give the chickens a few facts to day about eggs.

Altogether we have 6, Annie (top three at different ages) Ruby (bottom left), Edith (bottom left), Violet, Mabel and Peggy. We do have a goose but I don't think I can incorporate her into the book.
