One big happy family

Hi..so I have a question....i have 3 females ones about 6 weeks the other two are a year old ...I also have a male pig who's a year an I just got him neutered so he can be a part of the pack. I was wondering if there's a certain way I should house them. He's in his own cage in the same room but when I put them all togather whT should I expect lol.

Do you mean is there a certain way you should house them before you bond them?
During bonding and the weeks afterwards, You should expect all the normal dominance behaviours - mounting attempts (sows will not allow him to mount them until they say), chasing etc.

Firstly you need to wait until 6 weeks after his neutering operation to be 100% sure he can't get the girls pregnant.
Then the bonding guides linked to above will tell you how to bond and what to watch out for.

The cage size guide below will give you advice on how big the cage needs to be, but you need at least a minimum of 2ft x 6ft for 3 pigs.
