Anyone dealt with pitch in feathers? I kept seeing one New Hampshire Red constantly dust bathing. I thought her feather's were just full of soil that she hadn't shaken out, but while watching her preen, she kept picking at that "dirty" area. That when I realized it was pitch. When free ranging, they sit under a Doug Fir. These chickens are 17 wks old and I can't pick them up (they don't like it).
