Okay, those extreme close-ups of whatever it is are fascinating...but...hard to look at. Awesome photography!
I'm not completely sure what they are, they appear to me to be tiny maggots as well - that would be my guess if I absolutely had to make one. They're not mites, and too large for lice.
If it helps any, I saw similar "bugs" in the poo pan in one of my pens the other day; I use a 2x4 perch, and about 8" underneath I have 2 concrete mixing tubs with pine shavings in them. I removed them one morning, and by that evening, the poo was all sort of disintegrated looking and filled with these wormy things. I thought for sure I had wormy birds in that pen, but come to find out, it was fly larvae.
