Too soon for Rat Pups?

[Kinra]

I got 2010s 1400g breeding, small meals every 3-5 days for me gets them up faster than larger meals.

Are they early or late 2010s? I have a couple of August 2010s that are right around 800-900g, but I don't see a need to feed them every 5 days. Once a week has been working just fine for me.

I haven't been doing this for very long so I don't claim to be an expert by any means, I just regurge information that I've read several times.
