It should be able to take a small newborn pinkie with no problems. I have a hatchling splendida and I feed it pinkies that are hours old. But then again I breed my own mice and have easy access to them. If you have a local pet store that you get your feeders from, give them a call and tell them to call you as soon as any of their mice have newborns.
