what is up with my feather duster

[Namscam]

I have a large feather duster that has been in my tank for about 2 weeks now...I bought it from J&L and its doing fine and all but the problem is that just a few days ago it lost its feathers,,it s like the feather part of it just fell of... I found the feather part of it behind some rocks...The good news is that the feather duster is still alive, the only thing is that it doesnt have any feathers...Its still in its tube. I can see its pinchers that it uses to hold the feathers...thinking that the feather part was dead I threw it away, The question is will it grow another feather or not??
