I ordered some silkie hatching eggs on eBay a few days ago, they arrived at my house to day. When I was candleing the eggs to look for cracks and check air cells, I noticed one of the eggs air cell was on the wrong end. My question is can I incubate it with the air cell in the pointy end and air cell up? The air cell is not detached just in the wrong end. Also how long should I wait before setting the eggs in my incubator?
