I had to use pine tar on my EE hen because she was getting picked on pretty bad by one of my bantam cochins. Well, today I noticed that the bald areas have a yellowish waxy like substance on them and it's kinda gross...no smell or anything. But I'm afraid she might now be developing some kind of skin "funk" or even a reaction to the pine tar...? I tried picking if off but it was waxy/greasy like. Anyone know what this might be?
