Life is hard for a piglet at the best of times. A lot do not survive very long.
But these little guys have the best chance ever with you and the @little-peppers looking out for them.
I'm not sure about your hogs, but the pigs i worked with would eat anything, including piglets, so you may want to look at separating them out and keeping them somewhere safe when you are not around to keep an eye on them.
I've learned a lot about these hogs lately, and I was impressed. I think that they will do well, but I sure do know what you mean. Thanks!
