I noticed my hen making a noise. Kind of wheezing or barkish. Looked on here and having trouble finding things (probably being very impatient). So, I googled it. I saw a video of a barred rock (like mine) making the same noise. The owner gave the hen some vetx. Does it sound like my hen may have this? Will the vetx help? Can I buy this at tractor supply? Sorry, I am new to all of this and upset she may be sick. Worried!!
