Thanks!

I did just manage to find this as far as faults to avoid, of course I don't know what these look for or how to avoid them! LOL:

Crooked or duck toes
Knocked knees or bow leggedness
Squirrel tailed or wry tailed
Short wings or angel’s wings
Short neck
Sunken eye or irregular pupil
Sparrow’s beak or crooked beak
And the most misunderstood defect, beetle brow.
pigeon keel
