Yes they are. Its a long interesting (well, actually not really interesting) story on who the father is. Seems mummy was 'friendly' with 2 males. I'm not terribly fussed, I was just after something reasonably priced that was different to the norm and on class 1. I think I got it. The odd one out was the only odd one. I purchased 3 to start, and although I wanted the 'traditional' kimberley colouring decided to be less boring and get the odd one included. I was offered another one cheap ($25) as it had a dodgy leg from a feeding frenzy so I took it as well. It seemed to be dislocated (I could feel it popping in the joint) so I gave it a good old 'heave ho' so to speak, and it was fixed and is now perfect.
They get veg every few days and close to as many crix as they can eat in one sitting every few days, so I expect they will be huge in no time. The good old bluey is way underestimated as a good reptile pet.
