I have a broody hen who has been sitting on 9 eggs for about 13 days, and today I came home for lunch and took her out of the nest to get food and water. Normally she eats and drinks quick and then rushes back to her eggs, but today she lingered. I had to go back to school, but I figured she would go back to them soon enough. I returned 3 hours later and saw that she was still off her nest, and the eggs were cold! The temperature today is around 65 degrees. I quickly put her back on the nest and she settled down again. Is it too late? Have they died? Is there any way to tell? Thank you!
