We’ve put two citrus trees in the chicken run. Any fruit we don’t eat the chickens can have.
A little cage around the trees will protect them from the chickens, and also make a good spot for a little healthy garden. Some nasturtiums will provide nitrogen-fixing for the citrus, and some garlic and chives around the perimeter will help to keep pests away from the chickens.
Hula hoops from the $2 shop in Ferntree Gully make a good framework for the cages. The tree in the foreground is an imperial mandarin; the one in the background is a navel orange.
