New here and I need your help. A week ago my wife noticed the biggest duck in our flock. Tucking his head close to his breast. I didn't think anything about it until today. I noticed he wasn't eating today. When I was giving our chickens and ducks a treat of meal worms. He acts like something is wrong with his neck. As the day progressed he became uneasy on his feet. Very lethargic. So tonight my wife and I caught him and moved him to a brooder box. We gave him Durvet Vitamins and Electrolytes several syringes. Now he keeps opening and closing his mouth like he is either choking or having issues breathing. Please see video
