Adult large fowl chickens eat 1/4 to 1/3 pound each daily, so if no songbirds, Chipmunks or squirrels are enjoying their feed, 8 chickens would consume 2 to 2 2/3rds pounds of feed daily, if that's all they have available.
They may consume less in hot weather.
The higher consumption occurs during cold weather.
My Barred Rocks consume around 0.22 pounds each during spring and autumn, but I give them 2 Tablespoons each of Scratch Grains daily extra as a treat scattered in their pen. I have the regular crumbles in a hanging feeder. GC
