Advice needed please. My female piggies were both pregnant when they came to live with me 2 years ago and each had 2 babies. They have lived very happily in 2 groups of 3 sows and 3 boars. 2 weeks ago after a very short illness one of my boars died. My question is, would this be a good time to think about neutering the boys and trying to bond them with the girls? If so how do I go about this please?
