"The goal is not to make money, but to satisfy an agricultural/educational need, while not doing extra work for nothing."
If the goal is not to make money, but rather one of education, then I would recommend that you consider offering a list of local, reputable, chicken breeders who might provide hatching eggs at a reasonable cost to individuals interested in trying their hand at hatching eggs. That way you can be true to your educational mission while also encouraging support for local breeders of purebred chickens.
While it is educational to see the process of egg/chick development, I believe that it's just as important for people to learn about the long term planning and responsibility that goes with caring for animals so that we can enjoy their bounty. I would think that the task of taking the time to consider what type of chicken is wanted or needed for the intended purpose (meat or eggs) would go far to ensure the hatching eggs and resulting chicks are a planned outcome rather than a spur of the moment and impulsive decision to hatch eggs for the sake of seeing them hatch.
All that said, I would tend to agree with speckledhen's pricing rationale.
