splash bantam cochin hens doing this

[SplashCochins/Plus]

I have splash bantam cochin hens doing this.
Shaking her head some times, scratches the side of her head then yawns like she has something in her throat then swallows. The birds were shipped in from out of state about two weeks ago.They do not act sick very active, eat good. Should I be concerned or what should I do for this?

By no means am I an expert, but shaking of the head, scratching the head and yawning are all signs of gapeworm. Try looking around here on BYC for more information it.

Here's a link for gapeworm treatment:
