Fungus on beak or what?

[GeezLouise]

I noticed this today on Louise. She is eating and drinking fine so I am not terribly worried for now. It has been so incredibly dry here, I’m trying to combat it with a humidifier but it seems to only do so much. Could low humidity be the cause? What are your thoughts?

Could it be from food she was eating? Maybe a colored pellet or veggie stuck in a crack?
