2 male Rabbits. Giant Continental x Dwarf Rex Otter 4.5 mnth

I have 2 male Rabbits that need new homes. Sadly they won’t live happily with dad for much longer. Born 30th June this year and are 4 and a half months old.
Little Blue - is all blue in colour, the smallest of the males, but has recently had a growing spurt.
Oscar, mainly blue in colour but with some Rex Otter markings from his mum.
Dad is a Giant Continental
Mum is a Dwarf Rex Otter.

They’ve had a vet check and are vaccinated.
Ideally if they could go together and be neutered that would be great as no rabbit likes to live alone. But if not, I’d be happy if they went to new homes that can give them lots of love and attention as they have been used to it and if for some reason it did not work out. I would have them back.
They live together at the moment and get on fine, but may get to a stage where they fight once they have reached full sexual maturity. They are used to children and dogs. I do have indoor cages that can go with them. But they do have giant continental in them so these cages could not be a permanent home as they may get a lot bigger in size. Can be viewed with mum and dad.
Thanks for looking, please ask if any questions.
