I got 3 Australian Langshan pullets a couple of months ago. They are great little birds - calm, friendly and lay about 5 eggs each per week, even now in late winter. One seems to have problems seeing things close up. She always pecks a few millimetres short of treats offered to her. She's worked out to go for the feed bowls, not scattered feed. Reading the threads here, it seems there's not much to be done for her, but if anyone has any thoughts I'd be interested to hear!
