I'm doing this project in school where you take an egg and put it in a capsule thing that you make and drop it off the roof of the school. If the egg isn't broken you get an A. You have to supply your own egg so I figured I could take advantage of my chickens and try to make them lay hard shelled eggs. Does anyone have any ideas on how to make them lay hard eggs? Or how to make the egg survive the fall? I haven't been getting many eggs lately either. Does egg production drop when it gets cold outside?
