I don't think anything to be alarmed about. If there seems to be some undigested grass particles, maybe chicken is low on grit in her gizzard. Offer her some grit stones from the ground if you can find some near. You can purchase chicken grit also. It is not a necessity to purchase if chickens free-range on mother earth. Some areas, may have limited availability, so try to offer what you can. I always offer Cracked Oyster Shells free-choice to my chickens. That will act as grit until it gets dissolved, and utilized as calcium. Does not serve the purpose of grit as long as other stones would.
