Is it gapeworm without breathing distress?

[Kriscam]

I have a 1.5 year old RIR who several times during the day will open her beak and stretch her throat 12-20 times and shake her head several times. She doesn't have any breathing distress, and is behaving normally in every other way. None of my other three are showing this behavior. Does she just have trouble getting her food down or do I need to get a fecal float test? Any experience with this?

Sounds like shes adjusting her crop
