Hi,
Can you get any closer pics of the eye?
Also what kind of hides do you have?
One of my girls scuffed her eyecaps when I used an unglazed terracotta hide - it went away with the next shed so I replaced the hide.
You can see a bit of the hide in the lower left.
Is there any white ring around the eye or, if you look at it side on, is the eyecap shiny but the eye still blue? Is the blue colour uniform over the whole eye or is it thicker in the middle and fading towards the edges?
