I noticed my kestrel had a crack in his beak. Tonight I noticed he was flicking his tongue out and a piece of the crack is "flaking" off. I have tried to reach my sponsor but seeing as it's later in the evening I have not gotten a response. If anyone has any advice on what I should do until hearing back from my sponsor I would appreciate it very much.
When I got my bird out if his box this morning his beak looked totally normal. After talking to my sponsor and a couple other falconers we have come to the conclusion he was probably sloughing off old material.
