Gapeworm? Respiratory?

[Krystalzimm]

Merida (one of our chickens as shown in the video) has been breathing heavily (like expanding her neck) more often, sneezing/coughing, head shaking, and possibly hiccups? She doesn’t “gape” it open and she has been eating normally as far as I can tell.
Eyes have seemed clear, but she sometimes gets mucous like buildup inside her beak. (In this video she has some yellow around beak, but I just gave them some yogurt with turmeric).
Any thoughts as to what the issue is? I don’t want to treat for gapeworm if it’s not that and vice versa for respiratory!

Replying to myself in case it bumps the thread. Could really use help.

I think it might be gape worm, but it could also be a respiratory problem. I would treat the whole flock for respiratory problems and if that doesn’t work then I would treat them all for gapeworm.
