A few people have been asking about the girls. They are both feeling better. I think last night (a week later) we figured out what made them sick. We discovered the grease trap on the BBQ was overflowing into the dirt around the BBQ. That would explain the rocks interspersed with the messes we found. We thought it was because Ethel tries to eat grass to make her tummy better that would explain it.
Thank You for you concerns!
