If so, I'll remove the bowls and have them forage, and make them toys.In that case and if there is no way you can reconfigure the furniture in your room to give the piggies the space they need, then as above, make sure you don’t add anything which is going to block their movement around the cage.
One really good source of entertainment is to not use food bowls at all. Piggies spend a lot of time eating and using a bowl completely removes their need to forage and makes feeding time a bit boring and mindless. Instead, scatter and hide their veg and pellet portion in amongst the hay, inside tubes etc so they have to forage for it and use their natural abilities.
I would certainly get new grids as a priority for safety reasons.

They have Time put of their cage everyday to play in their playpen.I understand you struggling to give them more space, but are you able to let them have floor time either supervised free roaming in a room or in a playpen?
I had no clue, thank you for all the adviceAs we mentioned, you don’t want to block free movement around the cage given it isn’t big enough, so I would cut another hole in the side of that cardboard box so that piggy can walk through it more like a tunnel.
Please dont give them that much carrot. If you are going to give carrot, it should only ever be one very small piece and they should not have if more than once a week. A whole carrot is far too much. Carrots should be considered a very occasional treat. They contain a lot of sugar so are very unhealthy for them.
