So my vibrant Ron Burgundy was fine this morning when I gathered eggs and 8 hours later I come home from work and found him under one of the nesting levels, sort of tucked in a corner. His coloring was a darker purple color but no signs of trauma. This is our first flock raised from day olds with no issues other than some pasty butt when really young. There are no signs of sickness in the coop. Any ideas?
