IMO, trimming or debeaking is not addressing the issue. If there is picking going on, there's something that's not right (I wholeheartedly agree with MissPrissy).
Please consider adding enrichment items to their enclosure; you did not mention how large of an area they are in; could it be that they just don't have enough room? I currently have 21 chicks in a dog kennel (like the outdoor type, wrapped in chicken wire) in my basement. I had it split in half to make cleaning easier. I noticed some picking going on, and took the barrier out to open up the entire 5' x 5' kennel; added a few large branches for them to hop up & down off, and a cement block, just for something else to do. The picking has completely stopped!
