I have a little bared rock hen who's about 27 wks old and has been laying for 2wks now. She was an every other day layer but this week she's laying a good egg in the am and in the pm she lays a soft shell egg. She then eats the soft shell, just hers she's not going after anyone else's eggs. Now that this has happened the other hens have started running her off of the food, we have been giving her extra oyster shells and calcium dust by her self. Any ideas on what's going on? No other symptoms of illness vet said she's healthy.
