I'm getting ready to set 30 eggs and have a question. I have a still air incubator, no turner. Last time I incubated eggs I put them in there but ya know how putting them on that wire, they tend to roll a bit? I hate that. I dont mind hand turning the eggs so my question is.....is there anything I can use inside the incubator that would hold the eggs to prevent them from rolling around on that wire if the incubator gets bumped or something? Thanks.
