Ok, so I got a Hovabator 1602N (the one with the angled edges, not the smooth ones ) on ebay. I tried to put a shoebox in it, and the top of the incubator couldn't close, so it was too small for a shoebox. A deli cup fit in there, but I want something that can hold multiple eggs. It also seems smaller than the one that has the rounded edges. Do I have the right incubator, does any one have the same incubator as me, what can you put in it? Also, do you put water in the bottom below the screen? The 1602n seems a little frustrating.
