Homemade incubator question...

[JessicaGrant]

My kids are building an egg incubator for their science fair, and are working on designing the egg turner. I have only ever seen a turner that goes 45 degrees (or is it 90?) from side to side with the fat end of the egg up. My son has figured something out but it rotates the egg around 360 degrees. Any idea if this will be harmful to the egg? I know that a few days before hatching they need to be upright, but they stop turning then, don't they?

They are building with Knex and I think they are being very creative, but I want it to work, too!

Any input would be very helpful! Thanks!

No, you don't want the eggs to rotate a full 360 degrees. That twists up something inside the egg (I don't remember what it's called). You only want to turn them 180 at the most and then back the same direction that they came from.

Thanks...back to the drawing board!
