Hi all. Just when all the hens seem to be laying, for the last 2 days when I've collected the eggs I have found what i would call a soggy egg. its clear it had a yoke but the shell is like a popped balloon. I'm feeding them on layer pellets (advice from the local shop, said it contains everything they need) they also get carrot peelings etc from the garden and they have a run thats about 5m x 6m.
Is this caused because they aren't getting enough grit or is it something else.
Thanks.
