Bad birdies and broody hens

I made the unfortunate mistake of uncovering ripe blueberry bushes. To my dismay they were void of anything blue by morning. I had been showing the bushes to friends, as this year marks our first blueberry harvest. What a shame! They are now recovered, but the majority of this years crop was stolen.
I then realized I have even bigger fish to fry. My don's hen, General, has been acting rather strange this week. I noticed that she looks pretty fluffy and makes strange noises when laying her egg each day. I have collected several very warm eggs. Yesterday, I pulled her off the nest to forage with the others, but within minutes she was sitting back in the coop. Then it dawned on me that she has gone broody.
At this point its just comical, she screeched when the coop door is opened and acts like a real turkey. Today our other two hens wanted to harass her off the clutch so they could add to it. They are not acting like she is but they insisted on sitting on top of her in order to lay the eggs with the clutch.
Last night I ordered 10 rare breed hatching eggs. We will move her to her own place with her 10 plastic Easter eggs and replace them Friday when the eggs are shipped in. 44$ for 10, which is rather steep! I hope she hatches them all and that many are pullets!
