Hi everyone I have a rooster who seems to have breathing problems. The problem has been going on for almost a month now. First he lost his crow and seemed to breathe with his beak open. His breath smelt a bit odd too ....I thought maybe it was crop related.... Now his crow is back but he seems to get out of breath and sound like he is struggling to breathe.....when he is standing still he is fine It seems to get worse when the weather is cooler other than the weird breathing he is fine......seems happy scratching with his hens None of the other chickens are sick so I am guessing its not contagious ? I have no idea what is wrong with him .....I have been thinking maybe he inhaled something that has done damage to his lungs or that he has a cold of some sort ?
