It reminds me of the debate by free range farmers over free range egg farms and whether there should be an upper maximum size as there is a fear that very large units (tens of thousands of birds) could damage the image of free range eggs. it was around the time of Glenrath Farms planning submission for the world's largest free range egg farm.
It gets more complicated when you ask consumers for their view as they picture free range as a few hens in a farm yard and are horrified at the thought of 2000 birds in a flock (and that is at the smaller end of commercial with many flock lrger than this).
So what I am try to say is that I am for clear, honest labelling but for it to work, it would have to apply to all poultry products, including imports. Many birds reared in east Europe are stocked at even higher stocking rates.
The biggest challenge with labelling is how do you get across something that can be quite complicated, such as the different production systems in a easy to understand way. I am certainly against packaging that shows fields and trees for a product reared indoors.
