I'm thinking of putting together a hatching kit for educators for next school year. It would include a lease on an incubator & brooding equipment, plus the purchase of a bag of feed formulated for ducklings, half a dozen fertile eggs, and curriculum materials (I'm a former educator myself and can produce this stuff myself). An optional workshop (if, for instance, an entire school or teacher group were to do this) could train the teachers in all the essentials: candling (with actual partially incubated eggs to look at in varying stages of incubation--I'd have to have the workshop at my home), lockdown, how to use the materials, monitoring ducklings for comfort, etc. I'm planning to run a test run on the system with homeschoolers this summer, billing it as a homeschool summer project. I'd like to keep the cost to each classroom/teacher under $100--preferably closer to $60. They would be returning the incubator, brooder, lamp, feeders, etc. (and probably the remainder of the feed and possibly the ducklings) at the end of the lease period, so I don't have to completely cover the cost of those things every single time. They would pay a refundable deposit to ensure the return of equipment. What I want to know is, which incubator I should choose? I'd like it to hold at least six eggs (three is too few--too much opportunity for failed hatches and singleton hatches), be reliable and steady, and include the turner. It should also be inexpensive so I can afford to purchase several and rent them out, expecting a return on them fairly quickly. I want educators and their students to have the best possible opportunity for success. Suggestions??
