Wood mites

[Hopeful homesteader]

I agree probably just wood mites. If you don't see anything crawling on the birds. Also check at night after they roost some mites only come out at night and feed on the birds. I use a headlamp so I have both hands free to inspect the birds. Good luck and have fun with your flock...

Thanks, I'm already having fun with them I never thought I'd be excited about chickens lol
