I'm wondering why more folks don't just natural bedding for chicks? Things like dried grasses, leaves, yard rakings, etc. It's free, it's what they've be living on if their mama was hatching them and brooding them on the land and it doesn't hold any dangers for chicks. I figure folks in the desert climes may have trouble coming up with such things or maybe they too have dried grasses of some kind they can access?
I never did get the whole controversy in bedding materials for chicks...it's as easy as looking to see what they would be raised on if their mama was doing it and if they had access to the big ol' outdoors...then going out there and getting some of it. If it's too wet, dry it out prior to the chick delivery, but unless you've got a pristinely manicured lawn or land out there, there's bound to be dead plant matter to access for a brooder. It's sort of along the lines of giving them a clump of sod in their brooder...it gives them access to the environmental molds and pathogens in their future environment, right when they need the exposure.
