My dad has proposed that I keep the eggs in cartons for turning and lockdown. I thought it may be awkward to turn them while in egg cartons, but that having them in cartons during lockdown may be a good idea. Can you explain your method of tilting? I assume this would only need to be done if the air cell development is poor?
Before I purchased automatic turners I rigged up turners from cloths wire and the bottom of egg cartons. I bent the wire so the carton would sit on top of the bended wire which was bent in such a way that it would rock the eggs from being turned by a wire outside the bator. I used a small vise grip on the end of the wire to keep the turner in the position I wanted it in. They work great. just make sure to take the turners out and lay the eggs down in the bator so they don't get a little wing or leg stuck between any wires.
