Brahma hen who never laid an egg

[HensJoy]

Some hens are infertile or barren just as some humans are. She can still live a completely normal life, just without ever laying.

What bred of hen do you have a picture of in your posting? I have a two hens that are very similar in appearance. I had gotten them and was told they were where a year old, about 6 months ago and one has never, to my knowledge laid an egg. Of the two two hens I received at the time, which appeared to be the same breed, one lays an green egg every other day, but the other has not laid any. Is this normal? She seems healthy otherwise. She is the bossiest hen in the flock of four.
