Oh my gosh no! Don't debeak the poor buggers! Animals that have the proper amount of space shouldn't peck the tar out of each other like yours seem to be doing. Though it could be one or two overly aggressive birds. If that's the case, catch the culprit and remove them from the flock. Cover the bleeding wounds with something, otherwise the other birds with continue to peck at the red blotch on the back of the wounded birds. Quail are prone to being cannibalistic, from what I've read so if you don't cover their wounds or remove them to let them heal, the other birds will continue to peck at it.
