Weird lump on beak

[cackleberryandco]

Can anyone give any ideas on what this might be on my speckled Sussex’s beak? Her name is Winona and she is a troublemaker. It’s not on the other side and it wasn’t there before. She’s 11 months old, turning one in July. Thanks!

Open her mouth and look for anything out of the ordinary, particularly lesions. Also smell inside her mouth for a foul odor.
