weird growth on hen what is it??

[ChickenLove6]

I noticed this thing in my hens feathers. It kind of looks like where the feathers would grow but it is thick and slightly long. When I touched it a little big of watery liquid came out. What do you think it is? The pictures aren't very good as she kept moving sorry!

Is it on her back, beneath some feathers near her tail? It looks like it could be her oil gland.

Yeah! Thankyou I have no idea what an oil gland is, I searched it and the one on her looks like the one in the pictures :cd
