Free range chickens

Our chickens have a big area, but they are not free range, they live in high security electric enclosure which we take down and mow around then reconstruct. We would love to have chickens that can free range in the fields, but the evil fox might get them.
Various of the neighbours have actual free range chickens and we are going to give it a go so we hatched some chickens to try it out with. They have moved to the place they will live in an enclosure so they get used to being there before they move in to the real house.

I have just mowed and carefully checked the security of the chicken enclosure in this photo.

Here are the sacrificial chickens in their temporary enclosure. Fingers crossed for them!
