I have a 5 month SQ Silkie yesterday looked ok. Today her face and eyes have a brownish flakey looking substance that is covering her eyes. I also have another hen and roo the other hen does not appear to have any however the Roo has this on his comb. I also have 6 week old chicks in this pen, non of these appear to have any signs. The SQ Silkie cant see and is walking into the walls. I dont have any pictures sorry. Any Ideas?
