I've certainly got an odd ailment on my hands, and I hope some more experienced BYC members could help enlighten me on this one. Little Back story: I currently have a 5-year-old Barred Rock rooster, Oreo. Oreo's been suffering from not only a pesky and hard-to-get-of case of lice, but he's been stumbling for years now as well, which I had attributed to Arthritis (More on that part later). Today, after finally becoming fed up with his massive infestation that wasn't really being affected by Pyrethrin, I finally broke out the 'Big Guns' and got some kitten size flea/tick ointment and put a tube on him. As I was holding him after applying the medicine, I noticed a bunch of the buggies trying to flee past his thick clump of ear-feathers (I don't know the proper term). I pulled back the ear-feathers in the hope of getting the bugs out of his ear canals when I noticed that the whole canal was plugged up with some yellowish gunk! Literally filled to the brim with yellow crusty gunk. I managed to gently pry the dry, outer plug out from the canal, but there was still a bunch of softer yellow gunk crammed in there. I checked the other canal and that one was plugged up too! I managed to get the outer plugs out, which I assumed were hardened pus/infection balls (ugh!) but there was still a lot of junk in his canals. I'm super wary about just getting a tiny stick and trying to dig all the stuff out, but I really want to clean his ear canals out! I have a few specific questions I'm curious about, but any general knowledge of this topic would be a HUGE help! 1) What is the best way to clean his ear canals? Will a bit of mineral oil help? 2)Could his occasional stumbling be caused not by Arthritis, as I always assumed, but due to an inner ear infection messing with his balance? 3) If that's the case, could he be permanently cured? 4) Since I assume a one-time cleaning isn't enough, what the heck do I treat this with? What sort of dose? A great big thanks to anyone who can help me figure out this very unusual situation!
