I was not meaning to suggest that organic food production is not a good thing 
However, if it is deemed sensible to vaccinate against coccidiosis, then there really can't be much of an arguement against providing similar protection via feedstuffs, during the first few weeks. We are not discussing the widespread practise of overuse of antibiotics here.
Adding a coccidiostat to the highest quality of foods doesn't actually detract either from the quality of the food or the quality of the product.
Humans use prophylactic treatments all the time. There is a place for such treatments in all aspects of life and animal husbandry - even, in my view, in organic production. None of which is me suggesting that treatment should replace good husbandry.
Please don't get me started on a comparasion between regulation in the UK, and that in the USA 
 Beak trimming, the example you give, is a clear point where the UK is advanced. Proper husbandry, with some selective culling, maybe, effectively reduces the need for this practise to about zero. Ig God hadn't mean't chickens to have long sharp beaks, he woulda given them knives and forks!
While we are on the subject ..... declawing of cats is a practise allowed here. Ant Vet doing this in the UK would lose their license.
I am, as we all appear to be here, committed to providing the best care I can. I guess the discussion helps enlighten and educate us all
