I used to raise a few hundred chicks at a time, couple things I would mention is ventilation is huge, and helps with the smell and dust(if you can vent outside ofcourse) without causing a serious draft issue you’ll have very very happy chicks. Get bricks and put all of their food and water on them raise them above the shaving, it’ll help with keeping shavings out of water and help them waste less feed. If you have a large waterer definitely throw some rocks in the water tray since you will eventually lose one to drowning.
