Some would argue they were exterminated once they freed Ferdiad, but don't quote me on that: we absolutely don't know what happened to them next.

Personally I feel it would have been nice to have a bit more minor evil organizations like that. It's been so long we've seen them, I doubt we will ever heard of them again tbh
The Encyclopedia Eorzea 2 has a two-page feature on them, but a lot of it is "they are a mysterious doomsday cult, and being mysterious, we don't know much about them". Lots of speculation, but no real answers.

It does mention that the Lambs of Dalamud were generally surprised that Dalamud was actually a prison for Bahamut, and this caused many of them to abandon the cult. Whatever remnants who still believe are scattered and relatively unorganized.

As for their final fate, the EE2 doesn't mention their extermination at Amdapor Keep, or indeed any of their activities since 1.0, but it does mention that in the "present time", there are suspiciously similar cults among the Xaela, which may or may not be a revival of the Lambs in another location.
