I have had issues with soft shelled eggs for the last year. So, I was hopeful when my girls stopped laying for the winter that they would have time to refill their calcium stores and lay nice, hard-shelled eggs when they resumed laying in the spring. Well, they have begun and the problems are continuing. I have supplemented with calcium in several forms and vitamin D for months with only minor improvement. I found an article today which suggests that high concentrations of phosphate in their blood can cause shell-less or rubber eggs. Since peas are high in phosphorus, I am wondering if I have been causing the problem because I give them peas as treats every morning. Has anyone who gave peas daily had this problem? Or, do any of you give peas daily and not have shell quality issues? Any help would be appreciated.
