Piggy wheeking at new companion

[Ellza]

My adult boar is wheeking at his new baby boar companion through the cage divider. There hasn't been any teeth chattering or other signs of dominance or aggression. Should I consider that sound a good one?

Are you planning on the two living together in the same cage?
Wheeking is generally a happy sound, but you won’t know if the two will get along until you try the actual bonding.
