Thanks,
They seem to get on well together, so i will probably just get him neutered to prevent fighting. Its a good job the Netherland Dwarf is quite laid back then.
I think there would be enough space for a ladybun if i did get one as they have constant access to 4 X 5 foot shed attached to a 4 X 6 run, with occasional supervised access to the garden. Just out of intrest, is that big enough for 3? (Although I may leave it at two anyway)
