Mites can kill birds. They can hide is straw, generally not in hay. Most often they come in on wild birds.

oh, ok, so once the mites are in the cage, all the birds will die from them until my cage is mite free..right.?

It would be helpful to see a shot of your setup.

Exsanguination by blood sucking mites is not normally a rapid, one or two night affair (think vampirism) less energy, less thrifty, wt. loss, pale combs and wattles and, finally fading out.
Get a magnifying headset at a hobby shop and pick up a jeweler's loupe (good for IDing with some precision).

Definitely check after they've gone to roost (under wings/around fundament).

I read your posts in this thread: https://www.backyardchickens.com/t/690668/teeny-tiny-little-bugs-in-coop-but-dont-appear-on-chickens

opened up one bird that seemed to have no obvious injury, no mites found, some clotted blood inside under the wing area.
few days later miy husband thought he saw a few mites so we started the mite treatments...done everything and this batch died too!

Sorry you're having these losses.

You might want to be looking to other causes than ectoparasites at this point (might want to have a necroscopy performed - labs - if you lose another for no obvious reason).
