The other day I was bringing my hens a treat while they were out foraging. When they see me coming, they all run toward me knowing it's time for a treat. I was watching my silkie hen come around a corner and running and she just bumped into one of the raised garden beds, fell over, got up and ran to me for her treat. I guess her vision must be blocked by her top knot. Does anybody out there trim their silkies so their vision won't be impaired?
