I don't think you're a cranky pants at all. My father, God love him, has this whole thing thought out and actually helps his local schools. He provides the fertile eggs, but they have to provide all the equipment. The kids are welcome, with parental permission, to take home the chickens when it's time. He coaches, instructs and works with the students and the teachers. He gives all the information and help he can. Then when it's all said and done, he takes home the left overs. Isn't that great!? I love him for that. He found a way to accomplish the same thing for the students without hurting innocent creatures.
We raised rabbits as kids and my father taught us to be responsible. If we weren't, the animal was the one who suffered. I learned that lesson well and pass that along to my own children.
