How much should I feed?

[Mason Dixon]

I am raising 150 Cornish Cross chickens on pasture. I feed twice a day but I am wandering how much I should feed them. Should they have constant access to feed? Is there a certain poundage they should get a day? etc. Please help. Thank you.

Some people give them constant access to feed and others give them access for 12 hours, then take it away for 12 hours so they don't get too big too fast. I've always given mine constant access and they do fine.
