My silkie hen is about 9 mos. old and has been laying steadily for the last two months. About two days ago I noticed she had spent most of the day in her nesting box, but hadn't laid an egg. Since then she has continued to sit in the box (with no other eggs under her either so she isn't broody) trying to lay but has yet to produce an egg. She doesn't seem distressed, but I am worry she may be egg bound. I tried putting lubricant around her vent, but that hasn't seemed to help. Is there any way to tell if she is egg bound and does anyone have any suggestions for helping her pass the egg?? I just don't want to lose her!
