Hello, I have two female pigs that I adopted from separate spcas. Momo is 1 1/2 - 2 years (from what the SPCA was guessing ). Meeps is 1 1/2 years. For the holidays we expanded their cage to a c&c cage. Everything as been going great momo seems to be the boss piggy. Both pigs get along fine and are happy. But with the extra space I was thinking about adopting another female pig. I heard that baby pigs are Easier to introduce then older pigs. Since they will adapt better. But I'm not a posed to adopting an older pig I just would rather go with what would be easier for the piggies. Right now or local SPCA has a few 4 week old female pigs and an unknown age piggy. I would appreciate any input. Thanks!!
