My goose's beak

[Effrigfamilyfarm]

My goose's beak is turning black. Does anyone know why this might happen. It's the tip of the beak and about 1/4 of it. I can post pics if need

Mine started out black and turned orange, what breed is it?

Do you have a picture of his beak now? It might help to identify the issue.
Also does he have any other symptoms?

There are three things that jump to mind without actually seeing it,
1 something stained it
2 he injured or bruised it and there was internal bleeding,
3 mycotoxicosis.

Or most likely, it's just changing pigmentation.
