I have a RIR hen who recently went through moult. Previously, she had been scratched up pretty well by the rooster. Ever since she finished, she has been acting very neurotic. She hides out during the day, although she still goes in the coop to lay & sleep. When she is rousted from her hiding spot, she runs across the yard like somethings after her. When she gets to the other chickens, she stops. Any ideas??
