Chickens were born on the property, raised from purchased fertilised eggs – this guarantees that they are fed only organic food for their whole life. Although eggs can be sold (as certified organic eggs), this was not the primary driver for having the chickens. They were introduced to control a bug cycle that was destroying shelter belt trees and feijoa trees: the dreaded Bronze Beetle.
Selling eggs was not financially sustainable though, so once the problem with the bugs was solved by the chickens, they were all sold. In the meantime, the cost to deal with the Bronze Beetle problem was high due to the high cost of certified organic feed. The chickens had other benefits – they created biodiversity, and valuable manure which is mixed with chipped wood and cut grass to make soil.
