Hello, I am new to all this so if i sound a little uneducated when it comes to chickens please excuse. I have (what i believe) is a Barred Rock, still not sure if it is a hen or rooster, it is around 3 to 4 months old. I got it from my kids school, they were hatcking chicks there and after about a month let some of the kids take them home. Anyways my question is this: ive had this chicken (that by the way i am so in love with) for 2 months now and it just now started shaking its head whenever i talk loud, or if music is loud or the kids are loud. Its never done this before now and ONLY does it when thers noise made. Should i be concerned? Are we hurting its ears when it hears noise? Is this normal?
