My silver Phoenix hen seems to have trouble laying her eggs and the eggs come out kind of pointed and speckled. (She's about 10 month old). She stopped laying for a couple of months, but now she's laying again but not as frequently as the other hens. It takes her a long time to lay her eggs. Should I be concerned that she has a physical problem? And if so what can I do for her? Also during the times where she doesn't lay for weeks or months at a time, she starts acting like a rooster....crowing and trying to mount the other hens...any advice??
