My dad has some Silkies that are about 13 weeks old or so. One of them does this thing with her head that can only be described as...well...i can't describe it!! She shakes her head from side to side...not like she's shaking to remove a bug or something, but more like she has some really loud rave music going on in her head and she's keeping the beat. And I mean she gets into it! So much so that my dad named her Aretha. I have had chickens all my life, and raise them now as an adult, but I've never had a Silkie, and have never seen anything like this! As funny as it is to watch, I am a little concerned, because he wants to try to raise some Silkies, and if this is a neurological thing, do we really want to pass this along? Has anyone else ever seen anything like this?
