This morning I go to let the chickens out at about 6:30 AM and my golden comet hen was laying in the nest box making a loud crying/whining sound and I thought she might just be laying an egg. But later when I came home around 3:00 PM she was walking around the yard still making the same sound. Her egg was already laid when I came home. She looks like she is in perfect condition and her egg looks normal. I just never heard her make this sound before and I am worried. She is about 7 Months old and has been laying for about 1.5 months. There was no storm or anything that might of scared her. Please help I don't know what is going on.
