95% free range. Only when the weather calls for the run do they stay locked up. I do not stress the predators due to guard dog who loves his buddies . Roughly 200 acres but they know where home is and stay close. So truly free ranged. Compost, black soldier flies that I recently started producing for them and fodder. Other then that it's all bugs.
Great to find someone else that wants them to do a lot of foraging.
We just started our BSFL compost bin and I can't wait to start produing enough for feeding to the flock. Unfortunately it will likely be cut short due to winter but we're looking into winterizing it.
Currently we are feeding a whole grain fermented feed ration to the adult flock and the juveniles and those in tractors are on appropriate feed for their ages.
Our flock includes but isn't limited to Buckeyes, English Orpingtons, Cream Legbars, EE, SS, BR, Dominique (we lost the last of them a couple weeks ago- amazing foragers and fliers fox too fast), silkies, oegb, Brahma etc you name it we likely have, had or want to try it. LOL just about every year we try another breed or so. Our barred rocks are hatchery I'm not going to lie I don't care for them much.
Many people say silkies can't free range. Ridiculous. Some of my silkies are among my best flock foragers. Dh2B calls them worthless chickens but when a mouse ran out from under the quail tractor and an EE lost sight of it it was one of my silkie roosters that caught and ate it. Yes they may need a haircut but we've only lost 4 silkies to predators and one was a rooster that sacrificed himself. It sounds like a lot but it's not. I bet we've lost 40+ birds to predators in three years easily. I know it. We lost over 28 last year alone(most of those to the mink and rats before we figure out what it was). We seldom clip a silkie's crest feathers. It's true some of my silkies don't range as far but I do often see them in the closer parts of the field or farther away accompanied by a rooster or two. Silkies are hilarious after slogging through a muddy spring field.
In the future when we live in a place we are able I'm sure we'll have a LGD.
