One of my hens went broody 4 days ago. Yea. Yesterday I set up a place in a separate stall from the others put in a nesting box. lots of hay, food and water and after dark my husband and I went and moved her. 13 eggs...boy was I surprised. This is my first flock. anyway this morning I went to let the others out and she was out of her box and when I felt the eggs they were cold. I tried to coax her back in but she came out again. Should I be concerned or do something different? thanx judy
