Frizzle Rooster with lump on rump

[reichelhenitentiary]

this is the first time we have been able to catch our rooster Dwayne After a year and a half. He would always attack but he now is being bullied from his son Boots… we have enough ladies to go around but I’m worried because he has totally given up. He is so sad. Likes to let me hood him but I know he is in pain from this lump. I’ve been applying juju cream I make from tallow and other ingredients because it helps treat anything and everything. But need suggestions to see if this is something that surgically needs to be removed and can I do it at home with the correct equipment. I do not have a chicken vet near, nor do I want to spend the money to travel to one.

I think it might be an infected preen gland, is it just above the base of his tail?

It doesn't look like a lump. It's his tail de-feathered.

I do see some bruising or an infection. You need to clean that area and take a picture of it with better light.

I feel like a dolt now, that's exactly what it is.
Op, can you clean the area off and take pictures? I agree, he's being picked. What is your birds' diet and how much space do they have?
