I took a look at the bag of milk replacer I have for the baby goats when they come. I probably shouldn't use it though. It's medicated, and it would be a bad idea putting medication in them right before butchering.
If I had milk available I would go that route. But considering they drink a gallon of water a day, and will drink even more as they grow, I don't think I could afford to buy that much milk. I know even if I offered milk, they'd still drink water, but I can see them still drinking loads of milk because it tastes good. :) But next year, when I have lots of goats milk, I had every intention of giving the chickens some milk. Probably as an evening/early morning snack. I thought about the fact that I should watch their weight. But they'll be free ranging, so that should help burn it off some. I think the goats milk would be a great source of calcium. Also, as I raise the meat birds each year, I planned on adding goats milk to their diet. I'll have PLENTY of milk.
