I'm not sure if they will be avaliable or not. But if you do happen to find some, I'd recommend it. Their tails are surprisingly not the hindrance they seem like they would be in my experience
As much as I adore my silkies, I have to agree that they aren't the best choice for your set up. Mine have to be contained and not around other breeds for their own safety.
I do not have the slightest idea of what is avaliable in your radius, so forgive me if my suggestion just isn't possible...
