We keep chicks inside very briefly and then they go out to the big brooders so the dust isnt really an issue. Chicks are gonna make dust regardless of what bedding you use really. Their down feathers create the majority of the dust as they molt. We raise lots of chicks each year and have always raised very healthy fowl. Most battle crossed pullets are culled as soon as we can sex them to cut down on the unnecessary extra to brood. Once the chicks are moved to grow out pens they get straw. Once they are feathered we free range them until the stags start cocking up, then they go in stag pens with straw until their spurs set, and then they go on tie cords/barrels. Sorry Im rambling. Lol
