I need urgent help!!!!

I was taking picture of my chicks because they are 3 weeks old today. I went to go get one of my duckling when the other one walked right off of the "stage" thing. So I was paying attention to her. Well, when I closed the brooder, I closed it right on top of one of my chicks. Now she is acting all lethargic. I don't know what to do, I'm only 13 and I'm already crying. Please!

Well, it's only been about half an hour and she is already doing better. Although, I don't know is that means anything. A couple of years ago, I got my first chicks, and my cousin and little brother got them. Left two dead, two completely uninjured, and left one barely hanging on. She was acting the same way as this one and seemed to be improving. My other cousin heard her freaking out, she was running around the brooder peeping. So she put her back on the little blanket below the light. She did not make it and died less than half an hour after that.

I just mashed a boiled egg for her. She tried a little bit, but not enough to help her. She won't eat or drink any thing.

Well, I've got her in a box in my room. I can't really watch from across the room because the brooder is outside and the other chick are out with my ducks (They are separated by a wire fence type thing, not where the ducks can get them). Should I put her out with them, put them back in the brooder and put her in there too, or just leave her where she is? Thx

Okay, I put her back in the brooder with the others. I put the boiled egg in there and some sugar water. She seems to be doing fine now. Not as active as usual, but still more active than at first. I put her in there and she went straight for the food, so that's a good sign. Thx for the advice :D
