Approximately how much chick grit to use

[Northern.Ontario]

Im getting 100 Cornish cross in a couple of weeks. How much chick grit would I need to make available to them? What's the best way of giving them the grit? And roughly how much would they consume each week (pounds?)? Can I give grower grit once they reach a certain size/age?

Are you free ranging, offering treats, or strictly feeding formulated feed? If they aren’t getting anything else but chick starter food, they won’t need grit. Otherwise having a free choice container available is usually recommended. Probably a decent sized bag for that many birds, and just let them run through it for a few weeks till they are big enough to have standard grit.
