The boar has been with them for almost two months. We are letting them all live together until close to farrowing time and then separate him. I saw him mount Mera a few time and has since left her alone for the most part, she's gotten round so I think she's pregnant. Narie I have never see him mount her and she's not as round as Mera, but she does seem like she's getting rounder so I don't know. We'v had a really hard time telling if they are in heat or not.How long were they in with their boar? In my experience he will stop actively chasing them, and trying to mount. He may still flirt a bit(nudging their bellies, talking to them etc) but he won't be pursuing them. The girls also won’t come back into heat and will start to get round after a few months. Pigs have a very short gestation and I find most start showing around the two month(a little over halfway) mark.
