What are the pros and cons of tilting vs turning eggs? I borrowed a small homemade 'bator that I'm going to put my first batch of eggs in later this week. My friend built a pulley-style turner that will roll the eggs from one side to the other, but I've been reading on the egg carton threads that there are benefits to leaving the eggs in a carton, big end up, and tilting them instead of rolling them. Any thoughts on which is more successful? Rolling them doesn't allow the air cell to stay upright, which I understand aids in the chick developing with its head at the right end. But rolling them seems closer to what a broody would do with her eggs naturally...tilting not so much a "natural" movement for an egg in a nest. Thoughts?
