So I have a bit of an odd situation. Two of my hens set on one nest, then one of them went with the baby chicks that hatched and the other maintained sitting on the nest. After awhile the eggs under the silky were not hatching so we removed them. She is still broody. I'd like to let her set on another clutch of eggs. I want to make sure it is not dangerous for her to set for two sets of clutches in a row. Is setting for 40+ days dangerous for a hen?
