I've been thru their wing files-- they are not any more clear than the questions I am asking. There are simply notes on wings that say "bad wing" or whatever. But if you put a fine point on it, a lot of them don't really know either-- BUT they can spot a bad wing. Now I can too.... but I want to know what exactly constitues a split and whats going on with my birds with all the feathers growing in the same direction vs the one that has growth in two different directions.
I hope you have something to tell us soon! :)
