I am just curious, I had never heard of them hatching standing up until I came to BYC. Never actually thought about it. I have been standing them up in egg cartons I cut up just for hatching, but I I am thinking of lying them down instead. I find the egg cartons take too much room once the hatching starts and I am thinking lying down the other chicks will push and roll the eggs around stimulating those that are lazy hatchers. I am curious as to what others do and why.. Thanks Ralphie the First from the Duchy of Duluth.
