Out of 9 chicks more than half started to develop this white spot on their beaks, in between their nostrils, at 3 months. They're silkie/orphington mixes so I don't know if this is a breed thing. My first thought was that it was an infection or disease but Google has shown things way more serious than this really is! If anything the spot is just a miscolor on their beak; no tumor or anything. They don't seem sick, or even respond to the spot being there, but considering multiple chickens have it I don't want it to end up being something serious!
I do NOT have clear photos of it but I do have: http://fc01.deviantart.net/fs71/f/2014/352/f/d/chickens_by_bolthamos-d8acr5v.png
which includes the early stages of the spot and a bad photo of the spot now. (its all white; no green/yellow tint like in the picture)
Is this anything to worry about?
