Balance between feed and vegetation

[zm_hamdana]

Hi,
I have a flock of chicken, which I provide feed for and are also allowed to graze around within an ample space that is covered with different types of grasses and shrubs.
I know that an adult chicken eats between 100 grams to about 120grams. So, if a chicken can graze as they wish, is it ok if I reduce the quantity of feeds I provide? If so, what grams of feed per chicken are acceptable?

If these are layers then a well balanced feed should always be readily available. They will only eat what they need. If you are talking about meat birds then someone else will have to chime in because I'm not familiar with feeding growers.

My hens only Free Range an hour before sunset daily, but have access to dry Crumble feed all day. . Yeah, there's a hanging feeder past them fluffy butts. That's them chowing down breakfast after turning on the lights.

In the summer they consume about 100 grams/3.5 ounces each. During a heatwave less feed, 35c/90s Fahrenheit.
During winter they consume about 150 grams/5.3 ounces each. Even more feed during extreme cold, -10c/ teens Fahrenheit.

They also get Scratch Grains scattered in their pen.
One tablespoon each in the summer, two tablespoons each in cooler seasons. GC
