Giving her a bath will stop her if she is broody. Nipping at you is normal and the further along she gets being broody the more she will nip and even growl. Keep an eye on her to make sure she is sure then put some cheap hatching eggs under her for her first brood. Good Luck!
I just went out there again and now I'm wondering if she really isn't sick. I took her out of the nesting box and set her on the floor and she just kinda plopped down to sitting position. She is very very calm. Way more than normal. I took her outside to the water feeder and she didn't want any, so I dipped her beak in it and she drank a little. All this time still sitting down. The dog even came over and sniffed her and she just sat there. Normally she would run from him. Then I took her back in the coop, put her on the floor and got a handful of food and put it right infront of her and she wanted nothing to do with it.
