Ok because I am lazy when typing
AW= angel wing
TWT = twisted wing tip
It looks like AW, because of the upward turn, or what looks like an upward turn out and away from the body in the picture.
TWT is where the final joint on the wing physically turns. Take your right hand grasp your left hand fingers only and twist like ringing out a towel. Similar to this notion.
It's raining AGAIN today, but we have a Sebbie with TwT doesn't bother him one bit, will see if I can corner him between showers to get a picture.
You will find any waterfowl can suffer from AW, but TWT is something found in Sebastopols thanks to the curly feather gene.
Some think AW is genetic, some think it is diet related. I think it's a combo of genetically inclined (predisposed) and dietary. Too high of protien is thought to be a trigger for AW.
AW treatment:
IF the blood is still present in the feathers they can be tucked back into a naturally held position then vet wrap or even masking tape used to hold the wing in the corrected position. Often if you wrap and leave alone 3-5 days when you unwrap they will hold normal.
TWT:
Has no treatment, watch the feathers as they grow, make sure the house is large enough to prevent rubbing/breaking. You can trim them some to keep them from being snagged and broken off if it becomes an issue.
