I think that's pretty normal! I was a wreck the first time I had a doe due! Fortunately she was a champ and I didn't have to do anything. It's always difficult with a FF too. Or at least, I'm finding that this year!
When are your girls due?
The end of March or begining of April, somewhere between there. I had them at a friends house, who owns a ND buck, for about a month so I'm not positive of the exact due date. March 31st is the earliest possible date and I will be watching them like a hawk from then unti they kid. Since the buck was smaller I'm hoping it will be easier on them.
