Guinea pigs, even pregnant ones, don't build a nest like a rabbit or hamster. They do like to have some sort of hiding place like a hut, pigloo or simply a shelf that they can scoot under or hop up on
Most guinea pigs will make their own nest in their cage as long as you are using bedding they can move around and don't have a cage with a wire bottom. You can always add a little extra bedding for them but let them make their own nest. This is a natural thing to them and it is used as warmth.
Not a nest as such but they need things to hide in like cabins and they should also have a bed each.
maybe a rodent iglo and lots of bedding and chew toys but i dont think a nests is worth it
No, but giving them lots of hay and woodshavings is VERY important!
Hope this helps
