I think I have a hen that is broody. I have never had this before. I actually thought she got picked off because I have not seen her in probably two weeks. But I found her today in the barn. She is sitting on a nest, the only problem is that it is on a hay wagon, probably 4 feet from the ground. What should I do? If she hatches out chicks can they make it down okay? Or, I thought about putting cardboard around her so the chicks wouldn't be about to get out and then catching them all and moving them to a safe location.
