When I do buy eggs, I go to the local farmer's market and actually speak to the people selling the eggs, yes I've been a strange one in a business suit, asking about the chickens, their living arrangements/conditions/treatment/feed etc like I was some hippy

As I have food allergies, I have to be careful about what I eat and I'm even to the point careful about what the things I eat .... eat, IYKWIM.
I'm the annoying takeaway customer who checks the free range status of chicken and pork and eggs in pizza, burgers, sandwiches and so on. I figure, if you don't ask, how will they know customers want it? At the butchers as well, I like to know that they know the farms they source their meat from. In our area I'm lucky. It's not cheap, but our local gourmet pizza place uses all free range and so do many of our local chicken takeaway places. One just switched from Lilydale free range to LaIonica and I am going to go in and tell them I won't buy from them anymore.
