fighting pigs

[KatieJean]

well its been just over 3 weeks since i rescued a pig from the AC. She was with males and is fat so she's probably pregnant.

I already have a pair, a neutered boar and a female.
I put them all on the floor together, and they all started fighting.
2 actually reared up and charged each other.
the male seems to get along fine with them.
but my original female gets very territorial, and keeps chasing the new one and biting tufts of hair out of her. so i seperated them.

my question is. should i keep trying to introduce them if she might be pregnant?
will this be too stressful?

but she also seems lonely being by herself, would that be more stessful?

and are there any signs to know for sure if she's pregnant?

Can you keep their cages near one another so she won't be lonely until you know for certain if she is pregnant? I don't know what the expert advice on this would be, but I wouldn't cause her the extra stress right now if she is indeed pregnant. Good luck
