one of my hens has this problem but her stools are dark brown diarrhea . i started her today on electrolytes and probiotic mixed in water. gonna get some yogurt and see if that helps she's had it for a week now. darn birds won't perch and prefer to sleep on the floor. never seen that before. as cold as it is up here you would think they would perch off the cold ground. they hole up in the straw in the corner. weird.
