ok I don't have time to read the entire thing but...

first of all, you can't leave crickets in the tank with frogs. they have sharp mandibles and will actually attack your frog. you could end up with dead frogs if you breed a bunch of crickets in the same tank that they live.

Second, during winter, you only need to feed adult frogs once a week. they hibernate and are use to not getting a ton of food during winter months. It will be fine to only feed them once a week during those months. during summer break though, you might want to see if you can have someone come and feed them a few times a week.
