On February 10th I noticed that one of my hens was sitting on some eggs. I have gone out there to collect the eggs from the other hens. Most days I have only been getting 1-2 eggs a day from the 3 hens that are not sitting. When I check on the hen that is sitting. There are brown eggs and blue/green eggs under her. But today is March 10th so 4 weeks or 30 days she has been sitting on eggs. I have not seen any chicks. There are 3 broken eggs next to her. So I don't know what to think or do. Any suggestions or help would be greatly appreciated!
