I had a Buff Orpington hen that went broody about a month ago. We tried to get her off the nest and she just wouldn't stay off. So, we decided to place some fertile eggs under her to see if she'd hatch them. Well, hatch date was August 20th and they began hatching on the morning of the 19th! She hatched 5 babies! She is very happy and doing much better than she was. Here is a short video I took this morning of them. I will get a better video here soon.
