My sweet, super spoiled bantam hen has gone half way broody. Is this normal? She's been laying in the nest box for about an hour or two, certainly not long enough for hatching, but flattens herself out and gruffs at the other hens if they disturb her. She's also been fluffing out her feathers and grunting at my husband, children, dog and cat if they come near her when she's not nesting. She sleeps in our house on the nightstand next to my side of the bed. When the dog or cat or any of the other human family members come near, she acts like she's sitting on a nest. She won't do this to me, but anyone and anything else. I don't understand why she's acting like a broody hen, but it seems to have nothing to do with eggs. More like a territorial thing??? Please advise! I want my sweet little cuddle hen back!
