I raise button quail and even this rack seems like it will keep thin in place. I’m excited to use it. If the smaller eggs fall through the middle of the white conturn rack, I’ll place some thing there maybe like a paper towel. But so far so good. I think the eggs will stay in place.

I bought this not fully reading the description. I got caught in the excitement of hatching surplus quails for meat and eggs. I didn't read only small/standard eggs would fit. I raise jumbos and even my standard hens lay larger eggs. These rails are perfect for new laying birds because their eggs would be smaller. With larger ones, you just have to space farther apart. I really like these rails. As others have stated I wish they didn't just rest in the chicken rails. But for the quality and price they are well worth the money. We like how easy it is to clean them too. Simply spray hot water let soak them wash off.

We love how the celadon eggs fit. We have higher hatch rates due to the gentleness of these turners. One of our turners was kinda jolting or shaking the eggs in turner. We found out that the rack hold the turners was slightly warped. We fixed the warped issue and now perfectly calm turning!
The rails just sit in the turner. It worries me.
I'd love it if they clipped onto the turner.
