Take Note Barley feeders;
Take a handful of good sound barley and a pinch of salt and prepare a barley broth by boiling it. Strain off the water and allow it to cool. Place in a drinking cup and let the bird have this in place of plain drinking water. Ordinarily, you will find the bird improved in a few days. It may be ready for a toss after a day's rest and a day of light feeding plus the barley water. I keep this barley water on hand during the entire racing season for those pigeons that return from hard long races exhausted.
