Can I just say talking to them works too. Firstly, I had been trying to talk my hens into going broody and I put lots of tempting things out there for them to feel the mood. Next my friend texted me and said can you please hatch me some little chicks again. I said to her that I've had a chat with them and the girls said that they are thinking about it. Then the next day, Wham! It worked -broody hen and not moving. I read her like a book! I'm starting to think that it is easier to read a chicken's mind and than my husbands!
