Yes, our chickens it was last fall very ill, they were partly naked on my butt and chest, everything was in high spirits. the veterinarian prescribed us a poisonous dip, but it also not walked away .. As we are new to this field, searching and finally found this product. So we regularly sprinkle diatomaceous this, just as with the spoon in the straw. The chickens have recovered magnificently, they look great. Very smooth and cuddly.
