Well, the update:
Only two hatched. One was very small and had splayed legs and the other was alot bigger with no physical problems. My two kids begged to keep both.
Sadly the one with played legs as it got older, was getting worse to the point it was going round and round in circles and had to be dispatched. Sometimes you have to be cruel to be kind.
The other one is doing fine, living the life of riley at present in a very large puppy playpen on the dining room table, only a few weeks left to go before it goes outside to join the others. We have called it scruffy. I will try and get some photos if I can prize the digital cam off my son.
