Bump under beak and black spot on foot

[thghtlssthghts]

This is the skin that starts right underthe tip of her beak. I just got her so I have never seen her without it if it goes away. Could it just be a bug bite?

Also, another one has something on her foot. It's only been a few days, but it doesn't seen like she's favoring the other foot or anything.
They were being pecked at at the farm they were at

gently press the foot and beak spot to check for any pain
