I did not mean switch to layer pellets now. I meant when you switch to the layer pellets at the appropriate time, then life will get easier. I never said put chicks on layer pellets.Feed waste is kinda par for the course when you have chicks. I let them make the mess, at least it's only a problem while they're little.
Layer feed isn't appropriate for chicks. If you can find all flock or grower in mini pellet form, that might be an option, though I bet they'll still kick it around somewhat.
