Thanks guys. 
I was looking closely at Laker's beak as well - He also has a crack - lower down & finer.
A friend of mine keeps asking if I file my bird's beaks. She does this for her Sennie - I personally think it is a bonding thing for the 2 of them - Percy's beak looks really nice. She files it gently every week - so there's no big file day. She does the tip as well as the outside. Her bird just lets her.
I did keep watch to see if it bothers him - no change in his enthusiasm for food. - I'm only giving them grasses today & they're happy enough.
If it is just a top layer - like I saw with Bunny [Grey] & Percy [Sennie] when her beak was being filed & probably what Laker had - then it will wear away.
They have plenty of places to polish the surface area. They have the cuttle bone, the mineral block, the wooden perches, the concrete & sandy perch as well - not to mention my headboard on my bed.
Scott - did Pogo's beak smooth out or does he still give those toys heck?
