I was candling some of our eggs last night and noticed one with its air sack on the side of the egg instead of the top. How will this affect the groth and hatch? Never seen one like that. We are on day 12. Some insite from some experencied hatchers would be great. This is only our 3rd one in an incubator and we are learning what to look for in th candeling process. Thanks for all your help.
