I have an EE who has been sneezing/shaking head since she was a baby and sometimes she yawns with no sound almost like crowing with no sound. She still does it & my other chickens sometimes shake their head but no silent crow, but less often. Does she have gape worm? (I live in Seattle) she also has not layed yet and she is around 30 weeks and im pretty sure is a hen but might be roo. PLEASE HELP
