Our prize winning Jersey Giant Rooster has been quite sick. It started a week ago with him just having a weak crow. Then he began gasping and shaking his head. He developed a cough/sneeze the next day. We have given him Tylan 50 and VetRx and neither seem to be working. He is breathing very labored but is walking around and acting somewhat normal. We finally brought him in and put him in a room where eee could see if he was eating and drinking. He’s not doing much of either. We have given him Nutradrench yesterday and today but he’s just really congested.. Anyone who can HELP US?? We’ve followed everything a vet has offered. It is NOT gapeworm. I have a video of him from 3 days ago: His poop is normal but he looks horrible. He’s only 13 months old and weighs 10 lbs. HELP????
