Did anyone hear about this? Sorry if I'm double posting I didn't search, but I just bought 100 lbs of Ace Hi scratch today. None of the mentioned ingredients in the article where mentioned on the bags, but I'm a bit freaked out. I have a small flock of free range hens (for the eggs). They did mention in the article that these kids where eating a dozen eggs each a week (seems a bit much to me LOL) but still....arsenic? Ya no thanks. Whats the point of raising chickens for fresh eggs if this is the case... http://www.grist.org/article/food-arsenic-found-in-utah-kids-urine-traced-to-their-pet-chickens-fe/ Should i be buying a better scratch? Can anyone recommend something? I live in Los Angeles. Thanks!!!!
