Pink Birdsnest problem

[BCWolfen]

I have had a pink birds nest frag for almost 4 months now. On one side it has a small patch where the skeleton had turned green. Its been that way since day 1. The patch has slowly been growing over the past few months and is now alomost all the way up the main trunk. I had hoped it would heal itself, but its becoming apparent that this is not the case. The other side of the frag has great polyp extesion!! Its looks liek a fuzzy little blanket they are so long.

There are a few small branches with 2 tips. By small I mean less than 1/2" in length.
Would I be better off trying to frag off these tiny tips and securing them to the rockwork in hopes of them surving? What are the chances of such small frags making it?

Thansk for the advice.
