Congrats on your piggies! So cute and I am excited to see baby pictures if Oreo is pregnant. I had a guinea pig called Oreo as well! I’ve currently got 1 called Pemba, since Oreo passed away. I know it’s not ideal he’s on his own but I’m not allowed anymore piggies. He lives in a 2x6 C&C at my dads and I can’t remember the name of his other cage at my mums but it’s about 140x80.
Also I think neutering is an excellent idea for Chunk and it does seem to be quite common in guinea pigs now. I’ve never had any neutered personally, but make sure you have a good guinea pig vet.
I’m sure you have plenty of treats too, but my guineas have all been obsessed with the Oxbow rewards apple and banana (you can get them on Amazon). Anyway I look forward to hearing more about Chunk and Oreo
