Came home from a day trip to find one of our 3 month old Barred Rock pullets bleeding from a nostril and acting very lethargic. There is blood spattered all over the place as if it was shaking its head to clear it or something. Do you think this could be the result of an injury, or is there a condition that might cause this? I tried to look in its mouth and didn't see any obvious injury, but the bird struggled, then got even more lethargic when I tried. I wiped the blood when I had the bird in hand and it does not appear that any new bleeding has occurred. This really doesn't look good, but I'm keeping my fingers crossed as we have a very upset little chicken owner here right now. Any help greatly appreciated.
