Chickens in Classroom

We are a small non-profit EE facility that happens to have a small farm (at this point community gardens and public apiary) as part of our property.  We are looking to add chickens to our farm, and to make this educationally feasible, we are contemplating getting monies to sponsor a chickens in the classroom program for local schools.

What I am looking for is input regarding this program.

I don't want to just have this be another embryology program, because that has nothing to do with environmental education or sustainable living.  My goal is to have the program focus on where our food comes from.  We want to have the classrooms hatch the eggs and rear the chicks in a brooder until they are too old to keep, at which point the birds will come to our farm.  If the class hatched layers, they would come out to the farm for a field trip, help collect eggs, learn about chickens on the farm, and take the eggs back to school, where the cafeteria can cook them up for them (or the kids can take them home to eat).  If they raised meat birds, when they come out for the farm field trip, they will learn about chickens on the farm and collect their processed chickens (we will have them slaughtered, cleaned and packaged).  The teacher can take them back to school and the cafeteria can make a meal from them, or they can go home with students, hopefully to parents who will prepare a meal to share with the class later.

Is anyone else doing a program like this?

We have some committee members who are keen on the Missouri chickens in the classroom program, which, as far as I can tell, is strictly embryology.  And then what happens to the chicks?  This isn't the kind of program I want to do.

Any thoughts or suggestions are welcome!
