The feathers of the geese and ducks seems shaggy/broken (can't think of a good description) and not as much sheen as last year. They aren't sick and they act normal, but just don't seem as 'pretty' as last year this time... They have water to swim in a few times a week. 4-H show time is in a month and they are definitely not looking they're best and will not go probably. I had been feeding them layer crumbles w/ small amount Calf Manna added but have just heard they shouldn't have high protein or calcium. Any suggestions appreciated.
