Are you mixing it into wet feed? And do you mix the two bottles together or just mixing separate. My chickens eat most anything I take out there in a bowl, love ice cream, yogurt, left over sweets such as cake, donuts.What i do is buy wheat germ oil and cod liver oil by the gallon. i mix a large cooking spoon of each in the feed nearly every day especially coming into the moult. it will bring a shine to feathers as good as anything else i tried. as well as being healthy for fowl it will put a show shine on feathers.
