I picked stuff out from under my finger nails with her beak. She laid in my hand and I was able to use her point beak to get something out and she didn't mind. I cleaned it all off and gave her beak scratches in return for it of course!
Actually I want to know why they like getting their beaks scratched so much? I know Kili definitely likes getting her beak scratched. She even enjoys it when i file it a bit. Sometimes when she has food bits stuck to her beak I scrape them off with a fingernail as well.
Anyone know about some of the weird things you see on their beaks? Not so much leftover food but kind of looks like a growth, barnacle, or whatever. Don't know how to explain it. Kili's beak looks good now so nothing to show but I noticed that when I bring her in to get trimmed, they scrape around her beak and pick off some bad looking stuff and the beak becomes very clean and shiny looking.
