Just a comment on the replacer formulated for kids. It isn't worth the money. I had a goat dairy for over 30 years and occasionally we had to feed replacer. We found that kids will blow up and die just as fast on the kid replacers as they will on replacers made for calves. Also, the difference in price between the kid replacer and store bought milk isn't much so you are better off just feeding store milk. We found that if we used a premium calf replacer, one with all milk products and 20% fat and 20% protein it worked about as well as anything. Also, feeding half milk and half replacer cuts down on a lot of the problems too. We made sure the kids were up on their entero shots and we made sure we had GasX in the barn. If a kid is going to blow up, it will usually do so shortly after being fed. If we fed the kids first, before doing other chores, we were still in the barn if a kid had trouble and we could treat it.
