@johannpiber I cannot say I see much difference. Since the cow madness of years ago we hardly see cows outside. The farmers have open stables and they can go out by themselves but prefer to stay in the stable. They seem to like 18C best and warm outside or cold they do not like. The stables are warm plus there are massage tools (?). You can kick them outside for the scenery but if they don't want.
Since years we can only buy bio eggs and those shops we have at least for 40 years or longer. Partly it is fake too, same what supermarkets sell. A free chicken is a chicken not in a cage but free is different. They are still packed close on each other and get shots to prevent illnesses. If you do not do that and they get ill you can clean them all up.
Food can still have the brand bio if pesticides are used but they are only allowed to use certain kinds and till a certain percentage.
I had chickens myself. To be honest my eggs didn't taste better and I don't know what is hidden in the ground and water either. Some were always fighting and they looked terrible as I bought them. I never saw pigs play except some of the neighbour, saw them hung upside down too after being killed.
