Bloody nostril now wheezing
It would be good to know if her nostril was pecked, or if she is having some bloody mucus from her beak. ILT, or infectious laryngotracheitis, a respiratory disease that can cause bloody mucus from the nostrils and the mouth, which can be slung around the coop walls by head shaking. Watch her and see if the others seem to be picking on her. ILT usually causes gaping or stretching out of the neck to breathe, along with coughing, wheezing, and other respiratory symptoms.
