I've seen this before on our previous rooster...but as he died of illness I'm paranoid with this fellow. I've seen this on show birds??? Is it normal for roosters? - it looks like something wrong to me! This guy is new to us, he had it when he came, I don't think it's getting better or worse, he's a lovely healthy bird in every other respect. Any ideas? Thought about dabbing it with a vinegar/water mix just in case... He's a black australorp cockeral that was in a breeding pen prior to living with us.
