A family member of mine killed a buck with these lungs. I thought it might be hemorrhaging from the kill but he seems to think they’ve been there a long time and appears to be disease.
No - but he did just pull a muzzy and four inches of arrow shaft from his upper shoulder blade which the deer was limping horribly because of. Could barely walk.
A few years back I had this and sent a picture to ODNR. I forgot the name they used, but basically it happens when the animal dies quickly. Send them the pic, they’ll respond and let us know.
