I appreciate all the feedback. I do have them in separate tubs now but still in the incubator. I don't know if this is a national issue but one vendor said they may not have any racks or very few due to supply of heat tape and the one that I ordered back toward the start of December is still about two month from being fulfilled. I wanted to have a rack for these little one but three of them have eaten their first meal and I am trying the other two tonight. All are in individual tubs and in the incubator without a heat gradient. I can only hope I go to repticon and they have a baby rack available.
