Hard Bump Under Chicken Beak

[HereChickyChickyOfTikTok]

Hello! My little Sunny has a hard brown deposit under her beak. It looks like dirt but it doesn’t rub off like a clay dirt clod would do. I’ve only noticed it in the last few days and I spend time holding her everyday. The deposit is hard and dry and very solid. I couldn’t find anything on BYC about it but Google told me it might be fowl pox. Please look at the photo and let me know what you think and what I can do about it. Thanks!

Hard to know what that is.

Could be a sore that has risen from sticking the beak through wire or a minor injury.

For me, it's something I would just keep watch on and see if it gets larger or changes.
