Fortunately/unfortunately i found out what happened; i have a male white palm turkey thats looking for a hen to mount and another of my geese has the same neck issue. Just her head is turned right as opposed to down like the other one.
I've seperated the offenderd to give them time to get over...
I have 4 white Chinese geese, not sure on all their sexes yet. The 1 in question (dead eye diana) is a goose, i think. She has the smallest knob and 1 of the smaller ones, they're about 5 months old. I've had them since they were 6 weeks old.
Back story; about 2 months ago she got an eye pecked...
