Hi One of my chickens is laying a egg with no hard shell somedays and then when she does produce a hard shell its very thin. So If i am not around to collect the egg it can get broken by the other chickens. I feed my chickens layer mash, they have greens to eat they have scratch mix and shell grit. So i am starting to think maybe there is something wrong with the chickens laying cycle as all the other chickens produce very nice egss. Does anyone out there have any advice for me.
