I have 6 BSL that have been laying for about 4-6 weeks now. Over the past few weeks we have been getting jello eggs and eggs w/ no shell at all. I am finding 1 or 2 a day. They are all on Blue shield layer pellets and I have oyster shells at free choice. They don't seem interested in the oyster shells at all. They free range for about 8- 10 hours a day then are locked in there run at night. I give them leftovers and treats daily. I have also been adding ACV to their water. Can anyone help me? Thanks!
