I went out the check on the girls this afternoon and the snow outside of their pop door was BLUE!!! It was exactly the same color as the stuff I put in the car for the windshield. I was about to really freak out then I remembered. When I went to the store between snow storms they were out of green cabbage so I picked up 6 heads of purple cabbage. They were given their first taste of it yesterday and today they are pooping BLUE!!! After the sigh of relief I had to laugh.
