Think my White Cochin is going broody!

[Hegatha]

So my white cochin has been sitting on the nest all day today and at night. I think she may have hissed at me even tonight lol. Shes only 6 months old and started laying six weeks ago is it possible for her to be broody already?? If so how long do I have to order eggs to put under her?
Thanks

ever since the first day my chicken laid 4 weeks ago she wants to lay on every egg and not leave. in fact the other chickens lay in the same spot so they lay and she jumps on theres and hers to. but I take her out, remove the eggs and set her on the ground. She would sit and try to hatch if she could but I find her right away and out she goes. she is fine the rest of the day .yesterday she had 4 out of my five chickens eggs under her LOL, out she went. she barked at me and walked away LOL
