Can someone help me understand chicken ears?
I never thought I'd have cause to say those words ever.
The feather muffs aren't ears, then? It's the fleshy stuff down and further back? So there's an ear hole in there somewhere?
Anything we should know about chickens and ear safety when treating wounds?
LOL Good question @CarolinaSunshineFlock Yes, the little feather muff hides the "ear hole" or ear canal - if you gently move those tiny feathers you will see it. Take a look at your Henry. The fleshy stuff is the ear lobe.
I'm not sure about the question of ear safety when treating wounds? If you are referring to this thread about @MissNutmeg rooster with the swollen earlobe, then you would want to try to avoid getting ointment or spray in the ear if possible, but a little probably wouldn't hurt. Chickens can get ear mites and ear infections, so sometimes dust/sprays, antibiotic ointments and even peroxide may be used in/around the ear as needed.
