weird mite things!?

[Painted Calls]

I see a lot of cracked corn, and I'm assuming scratch, on the ground beneath her.

Those are grain beetles.

First...I am not a vet at all but.....

I would treat her for mites/lice immediately. Permethrin 10 is what I would use. I would do a full clean out of the coop and spray it too. Then every flock member needs treated as well. If one has bugs more are likely to as well.
Repeat the entire process every 7-10 days for at least 3 treatments.

Poor girls comb is not a great color. She may have an underlying condition that made her weakened allowing the (looks like lice to me) to infest her.

Is there a withdrawal period for the eggs?

I don't think so but lets have @Eggcessive or @azygous confirm that. I defer to their years of experience.

Those bugs, my friend, are fleas!!!!

DE dusting or permethrin based flea spray is needed.

Also treat your cats, dogs etc too.

 

[Painted Calls]

They are most definitely not fleas.

 

[Chicalina]

They look very much like them to me. Maybe a close up pic of one that has been caught would help. Or if the OP can confirm if they walk or jump.

I can see the antennae and body segments. Two different type of beetles.

Those things look like beetles to me, but they need to be gone. It can't be comfortable for the hen to have them crawling all over her.
Treat her with the Permethrin, there is no egg withdrawal if you follow application instructions on the bottle.
Shovel up all that extra scratch/corn that's laying around and throw it away so it doesn't get moldy.
Gather your hen up and feel inside her vent for an egg. Feel her abdomen below the vent between the legs for bloat or fluid.

Feel her crop and monitor it to see if it's emptying overnight.

Her comb is drooping and turning blue which, IME, is a good indicator that she has a reduction in oxygen intake. She may be egg bound, but I would suspect that she's having some other difficulty like Peritonitis, cancer or similar.

If she does not improve in a couple of days with your offering supportive care (making sure she's hydrated, getting rid of the bugs and encouraging her to eat), then consider putting her out of her misery. If you put her down, do your own home necropsy if possible so you can learn more about problems that affect laying hens, if not, then consider sending the body to your state lab for necropsy and more information.

I exploded the pics and agree they are some type if beetle....or two types.

I also found this when googling to find chicken bug comparison pics:
