Tiny brown bal, is it a bug or some kind of mite or exoskele

Hello, I live in Pinellas County Florida, last night, my girlfriend got bit by many bugs in my house in a short period of time, she thinks there might be some bird mites from some chicks we got recently but I don't see any signs of mites on the chicks. We found this little ball in our bed and she thought it is a mite but I have absolutely no idea. It was in my bed, it is extremely tiny, I took a couple pictures with a microscope, one from each side.

Here are 3 pictures, 2 of it under a microscope and one just taken with my phone camera so you can see just how tiny it is. It's just the size of a spec of dust.

I would really really appreciate an ID of what this is so much, thank you!!
