One of my young Buff's is lathargic. Just sits. Not eating or dirinking. I broungt her in the house last night as we had our first night of 'winter'. I put her on a white towel in the bath tub and noticed her poop is very dark green semi- soft. Her eyes are open and she is alert but she won't eat or drink. I really don't want to loose this sweet little Buffie. Any ideas or possible Rx to help ? THANKS !
