You're right, there are a lot of different schools of thought on this, and pretty much any other topic you care to bring up. The good news is, chicks are tough and resilient. They survive pretty much anything we throw at them.
I use puppy pads only for about the first week. Then I offer chick grit, and about three days later I introduce dried meal worms. I change the pads daily, of course. Then I add pine chips. They don't seem to eat many because worms are better, and I don't worry about it because of the grit. They don't die. Good luck! ❤
