See the difference! Chickens help grow pasture

Day-Range (Free Range) Broiler Chickens [edited: updates]

Due to a series of losses to predation despite our best efforts using the old pastured-poultry style system, we have made the switch to a free range system in which the chickens are fed outside the coops and go outside to forage during the day, and are locked safely inside the coops at night. While we expect to lose some birds to hawks and other daytime predators while the birds are outside, they at least have a chance of running away. The chief problem with having the chickens inside the coops was that if a predator manages to get inside then the chickens have nowhere to run. In addition, there is a built-in security flaw in the mobile coops, because they cannot have a floors in them which would prevent the chickens from foraging. In our system and with our topography it was not possible to keep predators from tunneling under the walls of the coop and getting inside.

In our day-range system the coops are now entirely covered in half-inch hardware cloth, including floors. [Covered floors proved too difficult to move through the grass, so we took them out and switched to running an electric strand around the base of the coop at night.] However, since the chickens are only kept inside the coops at night when they are asleep, it doesn’t matter that they can’t forage through the floor. [Still true, but we removed the floors for other reasons.] They go outside all day and forage in a much larger area which is protected by a temporary electric fence perimeter. We still move the coops regularly to spread out the manure deposit and to give the chickens access to new ground and we move the entire ensemble including the electric perimeter every week or two. So-called “free range” systems which do not move the chickens end up destroying all the available forage in the area. We make sure to move ours so that doesn’t happen.

For the farmer, managing this system takes about as much time as a standard pastured-poultry system in which broilers are kept inside mobile coops which are moved daily or more. In our day-range system each move takes more time and effort. The mobile coops are now heavier, must be moved farther, outdoor feeders and waterers must also be moved, and periodically the electric perimeter fence must be moved as well. However because the chickens are able to free range, when they are younger and don’t eat as much we can move them every few days instead of daily, so on average it is the same amount of time per day. Also, when using the old system we were spending a significant amount of extra time attempting to keep predators from tunneling under the coops — ultimately without success.

For now, this free range / day range system seems to be working well. We’ll provide an update after we have seen it in action for another season.

Building chicken tractors 1

Functionality has inherent beauty? 

To raise our chickens outdoors on pasture while keeping them safe from predators, we provide them with mobile shelters that provide shade, protection, and feed and water. The shelter design has removable wheels so we can wheel them to fresh grass throughout the season and the chickens don't spend too long in one place.

The bottom of each of these "chicken tractors" must be flat. There is no floor, which means the chicken manure fertilizes the pasture as they go. So the edge of the shelter must be flush to the ground so predators can't reach underneath it while the chickens are inside. Putting a half-lap joint into each bottom corner helps ensure it stays flat and there are no gaps.  And even though the other corners could probably be held together by just a few screws, putting in joints will make the structure stronger. Also, it just looks better!
