Every silkie hen I have shakes their head when I say their name or talk to them. I witnessed it for the first time a couple of years ago when one my hens went broody and I let her
hatch out the eggs. I would stop and talk to her several times a day while doing various tasks and each time I noticed that when I would speak, she's give that big poof of hers a
little jiggle. Scared me at first. I thought maybe she had some sort of neurological problem. That was until I discovered that she only did the head shake when she heard the voices of people she
knew, not for just anybody !!! Don't know if yours are that way too, but it sure cracks people up when they see it. Anyway, since then, every silkie hen I've had has done
the little head shake-shake-shake thing (at least when they're nesting), so perhaps it's a little known silkie trait.
Either that or the entire breed must suffer from some sort
of neuro issues (which I highly doubt)...lol !!! So I just chalk it up to their cuteness quotient and go on about my day (with a big smiling grin).
