Hard to photograph but Frizzled cockerel has a strange, raised (couple of cms high) , white spot on his back where the tail feathers raise from. It is red at the base of the spot and seems uncomfortable. Any help would be appreciated!!
Strange Raised White Spot???

That is likely the preen gland. Are you sure it is tender or inflamed? Here's a link about the gland, hope this helps:
One of my hens was pecked on by her female flock mates their first year - she even pecked at the bloody gland herself. She lived her first year with blukote around the tail - never had the heart to take a pic of her like that - but she was ridiculously funny with her blonde tail feathers surrounded by a purple ring :) And the preen gland healed and looks and functions normally.
Even my friendly hens do not like any physical exams.
Thanks. She is now a fully feathered fluffy BO and beautiful.
