I was outside checking on my chickens this morning and I noticed that one of the 8 week old silkies was falling behind in size. I picked her up and was shocked to see that her ears were swollen to the size of small marbles and filled with a solid white gunk. I brought her in immediately and carefully removed the caked on fluff covering the ear holes then worked the gunk out. I went over both ears with peroxide and antibiotic ointment as per what I read online. I set her up inside in a warm dry bin, Is there anything else I can do? She is still interested in eating and to my knowledge drinking. None of the other birds have any signs of this going on.
