My 5 month old pekin layed her first egg on Saturday, another on Sunday, monday, and Tuesday mornings - all perfect but when I came home yesterday, and was cleaning their pool and pen, she came into the pen and layed 2 more eggs, right beside me, the second quite smaller than the first but neither had a shell. She didn't lay this morning. Is this normal when they first start laying? I feed a mixture of wild game feed and layer pellets and have another bowl of free choice oyster shell. Do I need to do anything else for her? Thanks!
