Ch sicken with breathing issues

[Chickens-diva]

Hi, my chicken is breathing very heavily and having a very raspy sound. She’s also falling asleep (or maybe tired?) her crop is completely empty too. We tried giving a little olive oil incase something was stuck, which made it worse. We gave her water after and it seems to be better but she seems like breathing is difficult for her and she leans her head back and closes her eyes when breathing. Any help would be appreciated as she isn’t doing well right now. I can clarify anything if needed. She also has no appetite.

I added a video. It’s gotten better since that but she’s still breathing bad. She’s also pooping very often (roughly every minute but the look normal). She also seems to have regained some appetite but she’s still breathing badly.
