i know my silkies never made it back to the coop one night and it was darker than heck. being as scared as they were, they just snuggled up to the nearest thing and kept still and silent even as were almost stepped on them.
i hope the best for you. i hope your bird is okay and just perhaps hiding somewhere and will be back tomorrow.
I couldn't find my orp collective one night and was searching the trees and fences for them. When I found them they were huddled together in the middle of the pasture.
No sign of Primo yet, normally he would be out in the yard, sun bathing, and scratching at the ground. I called him, went into the woods...nothing, not even a feather
