Hello, I recently decided to buy some DE food grade for my flock of 3 hens and put a cup of it into 5 lbs of their feed. This is about a third of a pound of DE or 7% of the feed. But I recently stumbled upon a couple articles saying you just need 1 cup for 50lbs! So my question is, is it ok if I feed them this amount for now as I don’t want to throw away the feed. Or should I mix it with the 50 lbs of feed. The problem with the last one is that they would constantly be eating DE when I planned for them to just eat feed with DE once in a couple months. What should I do here?
