I cant say much about it, as I have only used it a couple of times so far. My chickens dont seem too keen to eat their pellets when this is mixed in. I have only had my chooks two weeks and at the moment they are very fussy on which scraps they eat too. So perhaps they will change their minds and appetites soon!
If you feed your chickens layers pellets apply a scoop to fruit and veg treats for better sucess. I coated some apple peices in spice and they love it!!!
