The Bros purchased a boar and sow late last year. The sow, Maple, came bred. When it looked like she might be ready to give birth, we moved her into the barn. And waited. And waited. Finally, in late January on a Saturday night, she pushed a piglet out. After several hours with nothing else coming, one of the bros reached inside and was able to pull a second one out. And then she pushed a third one out by herself.
She took to mothering, letting them nurse, making a nest in the hay for them to cozy into, and keeping an eye on what they are up to. They have been growing, like they should.
3 piglets is a very small litter, even for a first time mom. 9-16 would be a more common size. But they all survived. And 100% survival rate is excellent.
