Respiratory issues with broody chicken

[Kdreamer]

My broody bantam hen is sneezing a lot and breathing sounds gunky, how can I treat her? I did research and asked around in a FB group but there were no responses.
I went to tractor supply to look for something they told me to just let her be and if she dies, she dies.
I have separated her from the others as soon as I saw the symptoms, got vetRX and am giving it to her. I've never dealt with this, is there anything else I can give her? I want her to get better and continue to care for her eggs and be a mama...Thanks in advance!

Tractor supply may have given you a harsh answer, but it is based on reality. I hope your meds will help your hen
I had hens develop respiratory issues, and then crossed the rainbow bridge. I know it is sad. It is good that you separated her from rest of flock. This way the disease does not spread to them.
