OK this is more a gripe then anything. I have 2 year old layers that are slowing down on egg laying and some of the eggs have a soft shell. I feed them layer feed and include oyster shell on the side. I get some eggs that look to be membrane only or really thin shell. I do not feed them chicken egg shell because egg eating pops up now and then. The only change they have had was I got rid of a rooster who was a psycho, always raising the alarm over nothing and causing great stress. My girls were egg eating but that stopped once he went to the pot. The other thing was mites, I added DE to their bedding and that was that, no more mites. Anyone else have this problem?
