FYI, my hatchling rat snakes are eating either 1 pinkie every 5 days (unless in shed, then nothing until after) or the older one takes 2 pinkies about every 7 days.
It's very obvious when they're "ready" for more...When they bump up to fuzzies, they'll be on just one at first, then 2 as they grow, etc.
I don't really need a picture...I've raised plenty of king snakes & I trust your judgement anyway. 2 pinkies every 5-7 days should be fine.
