    My girls began laying recently and their egg shells are rock hard. Like, I've read of people have the opposite problem, and I guess it really isn't a big problem I would just like to know what would be causing it? I have started giving them layer feed, but even before then the eggs were ultra strong. It seems to be most all of my eggs, not just from one specific breed. I have a very mixed flock. Well it's not a real emergency or anything I was just wondering what you guys think. Thanks.

    funny you wrote this, one of my girls started laying a few days ago and I was surprised at how hard her shells were... I was almost expecting something thin. Curious to see if there is a reason for this, extra calcium in treats we give?

    Nothing to worry about there guys! When pullets first lay they can lay double yokers, thin shelled eggs, the hard ones are a good sign of plentiful calcium and a healthy diet. Also bare in mind the smaller pullet eggs have less shell to disperse the calcium, as the eggs become larger the shells will thin slightly.

    Yeah, the shells tend to thin out a bit (although not as thin as chain store egg shells) as the hens age. I'd forgotten how hard some egg shells could be until my bantam girls began laying a month or so ago.
