Crowing
For a first time broody, I would give her about 8. It's very important that you don't give her more than she can adequately cover. And sometimes, the number of eggs a hen can cover is more to do with the individual rather than the size. I've got two Australorps that are about the same size. One hen can only cover 8 eggs. The other can easily handle 15. Some are just better at it than others.
