Spayed/Neutered

[BasilBarleyandMe]

So I have 3 male bunnies that have not been neutered/spayed and 2/3 of them can now spray pee, and 1/3 are becoming slightly aggressive and I would really like to get all of them spayed/neutered ASAP, 2 of the bunnies are about 4 months and the other male will be 5 months old tomorrow of today's date (6/17/15). So can I get them all spayed/neutered now? If not when?

Thanks,
BasilBarleyandMe.

At my vet they de sex from 5mths I think but I don't know for sure. Males can still spray pee even when de sexed, my boy marble still does it but less often now
