Thanks for your help guys.
I do think the pinkie was too big, but since it got it down I thought it would be ok. Its a learning process. I get smaller ones, and sharpen my knives...
I'll leave it for 10 days now - that's how long I leave adults when this occurs (not often I hasten to add) - I just hadn't realised you could leave a hatchling so long.
Thanks again, Skye
