Is it possible to add all mobs from a mod (ex. exotic birds) via config in one string?
Like:
"exoticbirds:all" = "minecraft:feather"

No, it is not possible as of right now, you would have to enter every mob separately. I have not thought about this before, but it certainly would be possible for me to implement a new config option, something like a mod whitelist, in the future.
