I have a female Pekin, Louise, who is about a year and a half old. She has been laying eggs just fine up till about two weeks ago. Two Fridays ago she laid an egg with no shell, just the membrane. Then she didn't lay anything till this last Friday, when she laid another shell-less egg. Has anyone else experienced this? If so, what caused it and how did you correct the problem? I would really like for her to start laying proper eggs again. Any help will be appreciated!!
