The answer to your question is yes. The event you have witnessed is called DELAYED IMPLANTATION. Most reptiles and some mammals have the ability to store sperm within their bodies for quite some time (in some cases up to 5 years!). This remarkable adaption enables the particular animal to give birth when environmental conditions are optimal. Sounds to me like your captive environmental conditions are optimal. Keep up the good husbantry practices! Michael

I found a Female Agkistrodon c. mokasen back about 6 Years ago. When I got her home I looked her over and saw no sign of her being Gravid, but 2 Years later I had 4 of the most Beautiful Baby Copperheads you would ever see, and she had not been with any of my Males. I don’t know how long she had retained the Sperm, but I do know the Year I caught her was not the best of Years for giving Birth. That Year was very Hot and Dry and it was that way all the way up into the middle of October, plus the Year before was the same. So, the only thing I can figure, is that she waited about 4 Years to Fertilize her Eggs.
Now I know this is not that unusual among certain Species of Snake. I have heard of this happening in a lot of our native Snakes, even with Oviparous Specimens. Names of the Species I have heard this phenomenon occurring in are, Rat Snake’s, Kingsnake’s, Garter Snake’s, Pygmy Rattler’s, Cottonmouth’s, Copperhead’s, and even some Species of Crotalus. So what you had happen with your Female is something rarely seen, but it dose happen. Count yourself lucky to have witnessed such an unusual event.
PS: I hope the Babies do well, and Grow to be Healthy Adults “Good Luck”

Crotalids are also capable of parthenogenesis, though its quite rare and the babies tend to come out a bit 'odd' looking.
