What’s wrong with Louise?

Hey all,

Seeking help with treating Louise. She started coughing like this three weeks ago, we thought it was random but it has persisted and gotten worse. Another chicken in our flock has it now too.

We just ordered VetRX. We out essential oils in their water today, and we checked her throat for parasites and didn’t see any.

Edit: her crop is also feeling squishy, but to be honest we haven’t had any problem with these birds in 6 years so we don’t have a reference for what her crop feels like when it’s ‘normal’

Any insights would be greatly appreciated, thank you!
