My wife and I are first time chicken owners and one or 2 of our chickens has begun laying eggs! We have 3 buff orpingtons, 2 white rocks, 2 dominiques, and 1 Easter egger. They are all 19 weeks old! We are very excited!! They are very tiny though, but the shells are hard. What should we expect to be inside? I read one post where someone wrote that there wasn't much inside of the first eggs. And info would be appreciated!
