We have acquired an older model GQF cabinet incubator and a matching cabinet type hatcher. They have been sitting in a shed unused for several years. Everything worked well prior to storage, but they were not cleaned. Everything seems to look in good shape. After we clean them, we'll test them to see if everything works. I have a few eggs to test. I don't know if I would really trust the incubator for the whole season though without doing something. What should we replace or update? Wafers, etc. I know the incubator needs trays. Which trays will we need for peafowl, call ducks and chickens( standard and bantam).
