Help my chicken stopped laying

[McCoop]

Hi I need some expert advice. My California White has been since July with no problems. She laid a shell less egg three days agi and yesterday she had a yolk coming out of her while she was in the run. She goes to the nest today but doesnt lay. She is eating and drinking but she seems to be losing weight.

The hens are on organic lay pellet and get oyster shell and scratch for treats...nothing has changed in her diet.
Help...could this be serious?

Definately something wrong.... Have you wormed her? sounds like something wrong with her calcium department, the part of her that puts calcium on the egg.

sorry I cant be more helpful. How old is she?

She is nine months. She was laying about five days a week. Still nothing today and she isn't broody.

Thanks for responding!
