I have looked back and find some conversations from about 10 years ago that seem to recommend a weaning age of 5-6 weeks that works best for both piglets and sows. We have a chance to buy 3 week piglets worth the money, but I am leary that they are too young to separate from mama. My husband thinks the seller will keep them for two more weeks, if we pay now. This would get them to 5 weeks. What are the opinions/experiences with weaning ages? Thanks!
