I got my bag of food grade DE in the mail yesterday, and I went out to the coop with it and I sprinkled it on the coop floor cause it has been getting stinky in there, and then I mixed a very small amount into their food, and I also set up a dust bath. My birds love the weeds and cuttings we give them, and we usually just toss them in on the floor of the coop and they all come running to inhale them as fast as they can. My concern is, if they are eating the cuttings straight off the coop floor, then the DE is getting on the cuttings, and eventually into the chickens. Should I still be adding it into their food? The bag says mix it at a rate of 2% of the feed, so I am thinking if I mix it into a 50lb bag, I only need about 2lbs, or is my math that off? How much does everyone else give their chickens, and how much is too much? When they do start laying eggs (they are nearly 10 weeks old now), will too much affect their egg production? This is my first flock, and my first experience with DE. Thanks to anyone that helps with this issue.
