Was wondering if anyone could tell me, a couple of my hens in the past day or so are laying eggs without the hard calcified shell. I was wondering if that could be due to us feeding them too many other foods from the gardens and the kitchen and they are not eating enough of their layer feed and calcium??? We have been really letting them enjoy their fill from the garden and kitchen recently and thought that may be the reason. They have plenty of layer feed and calcium in their feeders, just not eating it. This is our first season raising chickens. Any pointers would be helpful.
