I feed on sunday. Always. When they shed on monday they have to wait until sunday for their first meal. Otherwise I wouldn't be able to get a regulary schedule to feed them between working, studying and keeping the house clean.
But I have only 16 cluches this year, so I have way less than Rich had in his worst seasons.
I think I would do it different with that many hatchlings to feed since it wouldn't be possible to feed all in one day.
