I have been trying to find 2 female PB's for awhile now for our Hobby farm, I was able to find a 4 month old male PB. I am wondering do males become aggressive as older? If the pig was castrated would it be more calmer? I would be willing to pay for it to be castrated to give it a forever home but I would much rather wait it out to find 2 females if a male is going to become aggressive towards children castrated or not. Also if it is castrated will it be able to live with a female or another male PB, I really want to find a companion for it since it will be a outside animal not a inside one. Also any suggestions or pictures of your shelter for your PB's would be great. Thanks!
