Bacon&Coffee! I can see by your name that you're all ready for breakfast & it's your hens who supply the all-important EGGS!
It must be the fact that we're having the manual transmission repaired on our truck that made me think "automotive" when I read the title of this post. I had to stop & wonder, "what do car parts have to do with broody hens?"
But seriously now, you'll have to watch your hen to see if she really intends to hatch that clutch of eggs. Often chickens will just like laying in the same spot without ever planning to incubate them. Often I'll find hidden nests with a dozen or more eggs, some that are the work of several different hens. They like to follow fashion which keeps them from having to think too hard & hurting their tiny little heads. They see an egg and go "Well, somehen thought that was a great place to lay so I'll lay there too!"
If this hen does intend to brood she will at some point, whenever she reaches her magic number or the voices in her head tell her to, cease laying new eggs there & want to set on the eggs all day & night. She'll fluff herself out, spread herself over the eggs, and yell at you if you try to get too close.
You have several choices:
Take the eggs & cover the nest spot
Take most of the eggs, mark a few to leave in the nest, and collect the fresh ones from there daily
Leave them there & wait to see what the hen will do
If you take the eggs you may still find them fresh enough to eat. Place them one at a time in a bowl of warm water & see if they float (bad) or sink (good). You should still crack them separately in a dish before eating, but they may be just fine.
If she does decide to brood you may want to move both her & the nest to a protected pen. Or make a barricade around her where she is. There are many posts on this forum about how to tend a broody hen.
I wish you all great success, let us know what happens with this clutch!
Edited to ask "Are at least one of your half-dozen chickens a rooster?"
