Ok so that is a Midwest cage which will be 47 by 24 inches. It isn’t big enough for two boars. It’s minimum size for two sows but boars need a lot more than sows.
You are likely to find you run into trouble with lack of space particularly once the baby hits his hormonal teens.
You will need a bigger cage - as I say 72x24 inches (180x60cm) is recommended for two boars to provide them with enough territory.
Perhaps you could get another cage like the one you have, join them in together (obviously removing both end panels) so it doubles their space.
I would also recommend that the two houses should also be replaced. We do not recommend using houses which only have one door in them. It runs the risk of one piggy trapping the other inside which can lead to fights. Only use tunnels and hides which have two doors so each piggy can get away.
You will also need another water bottle - always ensure there is two of everything in the cage.
I would also recommend you increase the amount of hay in the cage significantly and make sure hay is in two places in the cage.
It is better with boars to scatter their pellet (make sure you only give one tablespoon of pellets per pig per day and never allow constant access to them) and veg portion into hay so they have to forage for it and not use food bowls. Bowls can lead to food hogging by the dominant piggy. If it is scattered amongst hay then it keeps them occupied but also means both piggies have equal chance. If you wish to to continue using bowls, then make sure you have two bowls and they are at least one body length apart.
Boar pairs are absolutely fantastic (I have four boars myself - never in the same cages though, boars can’t be kept like that, only ever in pairs) but the thing with boar pairs is making sure they have plenty of room and never have a reason to bicker over resources.
