I have a rooster I keep alone and he does not have a "friend" to help groom in areas he can not reach, so I noticed this yellowish wax in ears about a month ago and used some vaseline to soften and cleaned out. He seemed to like it but I noticed today it was back. I kind of took him because he was mean and let this guy trade for one of my nice ones so that is why I don't leave him w/ any hens. Sometimes I supervise him out w/ a couple of hens that are not paired w/ a rooster but that is why he stays alone in a tractor. So is this ear wax? and is it common?
