I did, but usually cocci comes with blood in there poop. I talked with a the woman I purchased these hens from, and she said that it's common because chickens will eat lots of different things; nails, staples, pieces of plastic, styrofoam, etc.., Which I know she did because we insulated a part of our coop with styrofoam, that they can't get to unless the door is left open which my husband did the other day and they pecked and ate some. So it's an imbalance in her system. I've been giving offering her Greek yogurt, she ate some the 1st day, nothing the 2nd and then she started eating late today. Also giving her electrolytes in her water. I read here on BYC about giving them just a drop of neomycin (which is for larger livestock). It's supposed to take care of a bacterial issue. So no grains for her now, just yogurt, greens and a hard boiled egg and some mash. I was worried at first that maybe she could have had an egg break inside her because her vent was pulsing in and out. So I gave her a bath too, which she really liked.
I hope your girl is okay. I also read somewhere that this can happen because of molt, and stress. If you just moved, maybe it stressed her out. Look for pin feathers and try some yogurt. But not any with artificial sugars. Good luck
