I have a very broody chicken. This is my first one. She has been broody for a week. We keep trying to kick her off the nest but she goes right back on. I am nervous because the others are not laying because she wont get out of the nest box. I also broke my ankle and it is my kids and husband doing this. I feel so helpless that I can't get out there to help her through this. I only have 3 hens. I am nervous that she will not eat or drink enough. How long will this last?
