Ill let someone more experienced help you but

How long have they gone without eating the scraps and what kind of scraps are they? What size are the scraps? <-- Knowing that might help someone more knowledgeable help you out.

Good luck

Avoid onion/garlic scraps in your feedings, and be patient. Ground leaves are tasty to worms so it is possible they are going through that first. A gentle inspection of the bin, peeling layers back, will show you where they are eating and making castings. You can also tell by feel where they are concentrated/ active in the bin by simple touch (they leave slime ever which way they go).

Bear in mind that worms are actually eating very small particles of stuff including protozoans, fungi, etc and they are eating stuff we can't actually see a lot of the time. Most kitchen scraps need to go through a certain amount of decomposition by other organisms before the worms can eat the products of that decomposition.

The length of time needed for the worms to actively start processing the food depends on what kind of food it is and the conditions in the bin. Some kitchen scraps take a really long time to start breaking down, others - like melon - seem to be actively slurped by the worms almost immediately.

Are they crawling on the kitchen scraps or congregating under them? If they are, they're definitely eating them.

Are you seeing worm castings (poop)? If not, they are barely eating. If so, what color are the castings? If white or very light, they are probably eating the paper, else they are eating the leaves. Worms love leaves. Your food scraps are probably not yet ready for them. What are you feeding them and how do you prepare it?

I usually let the melon family waste sit for a couple of days or so before I fed them to the worms. Other waste even longer. My reasoning behind it: it is said that worms don't really consume the waste we put in the bins but rather the MO. So, if the WF (worm food) I put in the bin don't have enough MO in/on them, will it not take longer for the decomposition process since the worms will keep consuming these bacteria?

I store my WF in 3 gal. buckets with lid and I pre-mixed powdered eggshell. They don't really get anaerobic. I do get a sour or fermented smell sometimes but that will dissipate in no time once added to the bin.

What I have observed, the worms don't chew on the newspaper/cardboard. I suspect the mites and other small critters break down the bedding and worms get to it after, once it fits their little cute mouths, to coat it with whatever they have in their intestine and give us wonderful castings.

Actually, it works the other way around. The worms enable and speed up the action of the beneficial aerobic decomposers, by eating away the softened surfaces and continually exposing new surface area of the food to oxygen. That's why the exact same food rotting in a garbage bin will become anaerobic and smelly, but will not have much smell while being broken down in a worm bin - provided there are enough worms to process it and there is enough oxygen reaching it.

They are staying down in the bedding and not near the scraps of lettuce, coffee grounds, radish leaves etc. Nothing citric, no melon, onion or garlic. I guess they're munching their way through the bedding before having dessert. I'm now measuring the depth of the bedding to see if it's diminishing.

Is this a brand new bin? You haven't said how long the scraps have been in the bin or how long the bin has been going.

How big are the scraps?

Maybe a temporary thing you could try is add a light sprinkling of corn meal away from where you currently have the scraps and see if they eat it.

Also, have you heard about freezing your scraps and letting them thaw out before putting them in the bin? It breaks down the cell walls in the scraps and I read it makes the food more readily available to the worms (also blending the scraps can help).

Everything seems to be pretty normal except the scrap eating thing. This morning I found a couple of worms on the scraps so maybe things are going to normalize. Thanks.

Anyone out there raising Carolina Jumpers or Canadian Crawlers? I'm thinking about it for this winter.

Everything is probably fine - they do eat bedding, and will get to your scraps when they are ripe. Very normal especially if a new bin. Just don't add too much more 'food' (scraps) until things have settled down. As others have said, chopping or brushing or mashing/hammering into smaller chunks may speed things up a bit, but mostly a personal preference.
