It is truly sad watching the situation we have today regarding animal welfare. More about this is being highlighted to the public so awareness is increasing.
When you mention the poultry farms, the overcrowded conditions are atrocious like you mentioned how the chickens are kept in indoors throughout their existence.
Because of these farms, I made a decision many years back to only buy free range eggs just to do my small part.
I think that more attention does need to be given on how they are looked after to improve their living conditions but unfortunately it is a supply game.
