Too small?

Roaches shed their exoskeletons as they grow, just like crickets do, and sometimes the shed exoskeletons can fake you out because they look like dead ones. I've even seen the sheds get a static charge on them and jump around as if they were alive. Sometimes the only way you can tell the difference is to feel them -- they're light and crispy with no substance inside.

The white ones are freshly molted, and they are easier for your beardie to eat and digest because their shells haven't hardened yet. That's true for both crickets and roaches -- they're light in color right after they've molted, and then they darken as their shells harden.

It sounds like your beardie has a very healthy appetite, and it's good that he eats his veggies too.

BTW, If I remember correctly, I had the 1 second problem the first time I tried to watch the video too, but I was able to replay it and it played the whole thing the second time around. The new link seems to work fine.

Yes, they're supposed to eat more greens as they get older, They don't need as much protein once they get done growing (although there are some beardies who don't ever seem to figure that out -- ours is one who won't bother with greens as long as he can convince his human slaves to give him bugs. :roll. And if they're well hydrated (the greens contain lots of moisture), they can afford to dump some water with their poo to lubricate it and make it easier.

The first time my husband saw one of those white roaches he thought it was an albino. It does look strange until you get used to it. Your beardie may have already learned that the white ones are softer, so he likes them better and goes for them first -- maybe? :?
