My first thought were "red" mites but have read they come out only at night. When squished with white paper towel, you see blood smear. Never heard of "clover" mites but if they're "good" ones & don't bite chickens & humans, I'd leave them.
2017 I had mites (golden colored) but it wasn't bird mites it was "spider" mites although the guy at the AG Dept wasn't too sure, did not realize how many types of mites there are! He had a binder at least 4" thick of picture.
Whatever mites they were, never found any on the girls, in nest box nor roosts but they'd crawl on my feet. So started wearing boots, I have shaving on the ground/dirt. I sprayed with Permethrin, Neem Oil, Insect Soap, dusted with Poultry Dust & Sevin ... They were still present & still alive ... I did remove the girls before doing this. But the girls were getting frustrated in the brooder (8x3x2) so put them back in & sort of gave up.
The mites then started collecting in the corners under the plastic dog bowl I feed fermented feed in. I sprayed the underside with Raid every evening but hate using chemical so then tried Alcohol 91%, Rubbing Alcohol did not work. It worked.
This happed during the summer months, we had a very warm, wet & humid one but soon as it started cooling off, the mites were gone. Never saw them again
don't want to.
The worst part is they never left. 
Not very much, no panic. Got out the alcohol & spray the underside when I remove the food dish at night. Thinking now it's some kind of ground/soil mite that comes out when the ground is saturated, they're looking for a dry place to hide out? The guy at Dept Ag said not all bugs/mites are pests, there are good ones 
I don't like any biting insect, aside from the itching I swell up
