We recently adopted some adult rabbits. Two are neutered and one isn't. It is younger than the others, but is being aggressive towards the others and our DC. I realise this is probably hormonal, but I don't feel that we are being fair to any of them at the moment unless we intervene. Ideally we would get her neutered but at £100 we can't afford it straight away. I'm not sure what to do. Would it be cruel to put her in a separate hutch for a while? She could still socialise in the garden with the other two when we let them out?
