in what sense does free range cut down the costs tremedously? aren't you still offering your flock feed as they want it? Do you really see THAT much of a difference in there commercial feed consumption when they are out running around?
In what sense would it
not? Simple. If they are filling their guts up with foraged food all day, they will eat less feed when I feed them each evening. I don't offer free choice, as I want my birds to be hungry enough each day to forage for a good portion of their diet. They even do this in the winter. I have an orchard and large yard in which to forage, as well as neighboring hay pastures.
Do I really see THAT much difference in feed consumption? Well, why in the heck wouldn't I? My birds don't often "run around", they stroll along, scratching and pecking, resting and dusting, sunning and just being chickens. When I feed them each evening, their crops are about half full, which only leaves so much room for commercial feeds. Not to mention, garden produce in season, the apple crop in season and any food scraps I care to throw out to them.
I can't imagine why I would offer free choice to birds who already have free choice right out in the grass!
Now, imagine the same chickens confined to a coop and run, bored to tears and with nothing to do than gorge themselves on free choice feeds.
Heck, yeah, I save money! Why in the world wouldn't someone prefer to save money on feed by using this method? And the majority of my bird's diet is as natural as it gets, they get fresh ground on which to trod, and fresh air and sunlight~ which also saves me money in flock health.
