When I bred from my doe, she would allow me a look in just to check for any dead ones. She would put them outside the nest, so I wouldnt have to disturb her too much. Some does I've heard will kill their babies if you disturb them, my two does didn't. Depending on the litter could be between 1 and 2 weeks till you see them, I guess time of year too, as I didnt breed any to be born this early on. With my younger Rex doe, I was allowed to start handling them for short amounts of time from about a week old, she would come in and tell me when she'd had enough of me. I sold mine as pets so being tame was the big thing.
