My first clutch hatched on June 11th. They have been offered food several times...

One has eatin 3 meals (every time offered),
four have eatin 2 meals (skipped the first offering),
one has eatin 1 meal,
and one has not eatin yet.

They are all in the same rack in separate, but identical tubs...6 qts on paper, high humidity and heat tape around 89-90. All have been getting offered mouse hoppers.

What should I do about the one that has not eatin yet? Should I be worried about her and consider assist-feeding...or just continue to offer her food on the regular feeding schedule and hope she eats eventually?

Also...how often do you all feed your hatchlings?
