If they do decide to take pictures is should be from directly overhead and from behind (see image at the bottom) and they should try different lighting (indoor/outdoor bright/dim) and different camera settings to see if they can get the chipmunk pattern to pop... The autosexing trait will vary in birds, but if it's strong the white gene doesn't fully mute it in the chicks fluff and sexing may be possible...
The autosexing is one of the things I'm going to try and focus on with my White Sports... I'm also going to experiement with specific light colors to see what light color makes it pop the most...
This is the angle the photo should be taken at...
Here here!!
Love love love the legbars I have from your birds by the way but they've given me legbar fever lol must have more!!! Lol
