A homemade yogurt-making friend saved the leftover whey from the draining process for me to give to my pigs. They weren't too sure about solid foods yet.... now a few days later they're going nuts for it!
But as well as the food with whey, they found my boots to be fascinating.
I don't know if they were licking my boots for the dirt on them, but I've read that if piglets have a mineral deficiency you should throw in a shovel full of dirt. I did just that and they poked around at it. So I'll continue to make sure they can get to dirt and minerals as they grow.
You have to admit, that last picture is adorable!
