Sterile chicken?

[wxdude99]

I have 4 chickens - a BR, a golden campine, a brown leghorn, and an austrolorp. All of my chickens are laying regularly except the austrolorp. Is it possible she is sterile and won't lay eggs? After what I've read about austrolorps, I was hoping she would lay the most eggs. And the biggest. She's 5 1/2 months old. Thanks.

I would give her time. She may be a late bloomer, I had some hens that did not lay will 30 weeks old. Some being brahams.
