I have 8 new pullets that are of egg laying age. I saw my rooster mount one yesterday and she squatted for him. For the last half hour, one of the newbies has been clucking non stop and seems restless. She stops for preening, drinking water, and eating/pecking ground. Is she trying to lay an egg or is there something seriously wrong with her? She went in the coop for a few, then to a hiding spot for a few, then back in the coop, back outside all while clucking. Doesn't sound like a happy cluck either. Never seen this behavior in the 4 years I have had chickens. She is a Sapphire olive egger.
