How much feed to raise a sex link chick to 22 week?

[OkChickens]

I am planning on raising 75-100 RSL Pullets and figure out how much feed they eat. I am planning on letting them free range at about 10 weeks old on for most of the day. Has anyone ever figures out how much feed per hen it takes to raise them to 22 weeks? I bought 20 bags of chick starter yesterday and i know that will get me started. I estimate that they will eat 20-25lbs of feed to grow until 22 weeks old. Thanks.

I got this table off a feed bag it seems to come close to what I fed to raise mine.

Weeks of Age Feed Approx Feed Consumption for Period
0-8 Chick starter 4lbs/bird
8-20 Chick Grower 12lbs/bird

It you are planing to free range at 10 weeks then the amount they will eat obviously be less. Also i think they counted on little or no waste.
