All hedging plants should be cut back at the time of planting, people feel sorry for them and dont like to do it, but it gives them a chance to thicken from the bottom, if they are 6ft tall, cut at least a foot off of them. hopefully they will thicken, but with hedging you have to be cruel to be kind. When you see new shoots at the bottom, cut the tops back again. to be honest, if they were mine, I would cut them down by half, but thats up to you.
I planted a laurel hedge in 2012, 2 to 3 ft bare roots, i have cut back each year and they are now solid at the bottom, really thick,
Fertilizer wont help, they just need cutting. All that will do is make them grow taller.
