I appreciate the simplicity of your worldview and the strength of your belief in your power to change things - or that the change we both expect is coming will be in any small part as response to your actions.I understand your argument regarding corporations but corporations are held to certain standards regarding health and safety practices and when selling live animals it is moreso because of animal cruelty laws. I agree that boycotting will more than likely do more than a petition but the point is to make our voices heard. You can blame shipping, you can blame the weather, you can even blame the hatchery but when it comes right down to it the birds are not being kept in adequete heat or ventilation in those brooders. Its up to you what you choose to do whether you agree with others or not. I have my own personal thoughts on these brooders and I personally think they are cruel. I'm not trying to sway an opinion just trying to ask people of like minds to sign.
Its not worth my time to address your drive by reference to animal cruelty laws or health and safety practices. {Not a great source, and they have an obvious agenda, but its not a terrible gloss of the shape of the legal landscape}.
All the best to you and your efforts.
