The beak does not necessarily grow back. It depends on the extent to which they were debeaked. I have two sex-links, bought as ready-to-lay pullets at the feed store last year, who of course (sigh) came debeaked. Theirs have not grown back, although wear has made them a bit less blunt than they used to be. And they were not as severely debeaked as many are.
They do ok. But I still think it's terrible thing to do, and to me the solution to "our chickens keep picking each other apart because they're so crowded and unhappy" is NOT just to chop off the bitey parts
