For those who add Sea Kelp to your goats ration...do you feed it free choice, mix it with loose minerals or put a measured amount in their grain ration. The two new boers I have dont like the SweatLix mineral and dont touch it. After a recent post, I ordered some of the Onyx cattle mineral but that isnt going to be here for a couple weeks. I was hoping the kelp would make the SweatLix more palitable. Any feedback would be appritiated.
