After I was ready, I went down to see how the chicks were. There sat Carlie, still on guard! I was so blown away by that.
After cleaning some downstairs, I checked again about 30 minutes later. The sun had come up full blast, and Carlie deserted her post, opting for the cool shade of the side porch. Oh well, she did a great job for about 1-1/2 hours, so I can't fault her. Good job, Nanny Carlie!!
