"Acquire a Deep Crow Egg" quest glitch?

cuandur

I trying to complete "Acquire a Deep Crow Egg" quest where I need to "Find 3 Deep Crow Feathers". I have acquired 2 or the 3 but the last one is on a precepice which after I've killed the little fire daemons etc and stand close to the edge to pick up the feather, it tells me that "I cannot while in combat" but I have killed everything I can in this area but it still activates combat anytime I go anywhere near this feather. From what I can see there are only 3 feathers in this are and I have 2 so what do I do about the third?
