Heavy breathing - gapeworm or respiratory illness?

[A Swede in France]

Hi, my 1.5 year old brahma Cookie is breathing heavily, in a way that's making her whole body pulse. See video for an example from the front. See how her whole neck is inflating. From the back, her butt is also moving with her breath, and when she lies down her whole body is well... pulsating with her breath. She's otherwise fine - eating, popping, preening, foraging, laying, not lethargic, empty crop in the morning, no swelling, no wounds, no lice. Coop checked for mites. There's no wheezing and while she does open her beak more than normal, she's not really extending her neck or gaping extensively. She's not isolating herself. Nobody else (out of 14) is affected.

Wise from earlier respiratory infections we put her on antibiotics for the past five days, but there's no improvement so I'm starting to think it's parasites or a virus.

It's been a long time since I dewormed them because last time one got really sick right after and nearly died so now I'm afraid. So, parasites are definitely a possibility.

What do you think, does this look like potential gapeworm or should I follow other lines of inquiry?

I think you can see the video on this link, if not, let me know and I'll surrender to using YouTube

From my limited but recent experience, it doesn't look like tapeworm. However, she could have an airway obstruction.maybe she breathed something in while eating. Look up what to do for that? Start giving vitamins and boosting immune system with herbs just in case.
