Since the incubator/eggs need daily care & monitoring (watching temp/humidity, turning eggs several times a day if you don't have an automatic egg turner, watching hatch, etc.), you will probably want it at your house.
Can your Scouts do a couple "field trips" for candling, or even to come over when eggs start to hatch (can be a lengthy process, though, so may take some "coordinating" with the parents!!)? you could probably manage to make this something that both your son AND your Scouts can experience...
