I have a pretty good size flock of different breeds. One group is 4 Blue Splash Silkies that are about 5 months old and they have a 3-4 month old Slate turkey that runs with them (almost the same color). One of the Silkies has been waking up for the last 4 days or so with her eyes sealed shut with a crusty formation. When I clean the crust off it seems that there may be a green gooey under her closed lids (probably indicative of an infection). I don't see any tiny critters or anything but I can't figure out what I need to do for her. As far as I can tell she's eating and drinking fine. They are free range so I don't know that for sure. Anyone have any suggestions?
