What kind of bator do you have? I have a Dickey's and GQF and I bought duck egg trays for them. They kinda fit in the chicken trays but may fall out when your turner turns. I have a LG chicken egg turner that I use to put turkey eggs in while I collect them for the week for incubating(so I don't have to hand turn). I leave it on my laundry room counter and it stays about 68deg in there but it doesn't tilt as much as the Dickey's of GQF.
