All three of my silkie hens are sitting on eggs. They seem to be sharing the job. When one gets up, another will beak the eggs under herself. I've decided to let them be, but I'm worried about my smallest hen. She doesn't seem to ever leave the eggs to eat or drink water. I'm not able to fit any waterers in their little area, and I'm afraid to move them all for fear they won't sit in a new location. (It's day 8). This may sound silly, but can my little hen starve to death or dehydrate?
