Hi everybody and thanks in advance for any advice. My D’Uccle (sp?) has some crusty looking substance on his face. I have 7 birds in total, all are fine except maybe the Cemani but I’m not sure, it might be just dirt. I can’t see any little bugs or anything. All are eating and drinking fine and seem fine behaviourally. They all came from the same place about 6 weeks ago. Nearest vet that will see chickens is 70 km and closed today. Is anyone familiar with this? Thank you very much.
