weird mite things!?

I strongly urge you to get a necropsy done on Marmalade. Refrigerate her body until you can locate a lab.

There's a strong possibility you have an avian virus in your flock, and you need to find out what it is.

OP I think the mites are the least of your problems.

Lil peep (She was supposed to be a jersey giant but I think that was wrong) died from same symptoms like 3-4 weeks ago

Marmalade died just yesterday buff Orpington

and now I am noticing the leghorn (her name is Crackhead) her comb is turning a dark purple which was one of the symptoms both marmalade and lil peep had

I agree, getting more information by sending a body to your state lab is a good idea.

Post photos of the White Leghorn and her poop.
What do you feed including treats?
How old is she?

I advocate for every chicken keeper possessing a magnifying lens.

Good call, darlin! Adding one to our first aid kit based on your suggestion. Thank you!
