I've only had chickens for a year so I'm hoping someone will tell me that this is just something they do occasionally! I've got a hen, who is about 1 yr old, part Silkie. This morning I saw her do the head shaking thing for the 3rd time in the past month. She'll be standing somewhere, seemingly comfortable, not stressed or hot or scared. She gets a vacant stare and her head/neck swivel around about an inch repeatedly! Looks almost like a cartoon character doing an exagarated double-take. She came to me last Aug with tattered looking feathers and may be molting now. Has laid soft shelled eggs off an on during the last 2 months, interspersed with normal laying for weeks at a time. All other indicators seem to be normal Thanks for any help!
