My only thought, as Iām not as familiar with chicken diseases, is check her over very thoroughly for a missed puncture wound from claw or tooth. Something like that wouldnāt necessarily bleed much.
Cat and dog bites and claw wounds are also well known to create abscesses. What you describe sounds a lot like an infection developed over the time since the attack.
