Want to know a not-so-secret-secret? We've had a late hatcher living inside w/us all winter. She's 4 months old now, has a playpen inside and covered kennel outside where she & adults are acclimating to each other. But she still goes in her brooder in the evening to sleep (she's getting a new coop). She's pretty quiet in the evening, until my husband makes sarcastic comments to me, then she stares right at him and lets fury bellow. Then she turns her tail feathers on him, aligns herself on her perch and resumes quiet rewhistling.
