I just received my first shipped eggs and am going to set my first incubator ever. I decided since I was mixing eggs from different breeders, all unknown to me, that I would use an Oxine wash. As I was gently washing each egg, I had one that floated. I candled it an noticed the air sac was completely mobile and moved whichever way the egg tilted. I broke the egg and it looked "normal" inside, but then I've never really examined an egg all that close. There was no unusual odor. So what makes the egg float? Should I have left it alone and tried to incubate it? As I candled other eggs, I saw several that had air sacs that moved readily. Is this o.k. or a sign of trouble that I should eliminate before even starting? Any info is greatly appreciated. Annie P.S. Once in the incubator I will be using an automated turner so eggs will stay large end up.
