It took a while for it to work for me, but I suspect it was operator error. There is an app you can download to your phone and you point your phone to a carton of eggs in the supermarket or elsewhere and the app will tell you if they are cage eggs, barn laid eggs or free range eggs, and then the hen stocking density of the egg producer. The former information is usually on the carton but the latter, although legislated for, will not arrive for a time. 10,000 chickens per hectare of land is not free range in my opinion, and that is what our Coles supermarket free range eggs scanned as. We won't buy them again.
While there was media story, probably a beat up, that there is a shortage of free range eggs, there was no shortage today at Prahran Market, naturally at a premium price, as most things are at Prahran Market.
The app was developed under the auspices of the consumer organisation Choice and is called Cluck AR if you are interested in downloading it to your phone.
