Help! Mouth growth in hen

[Im_Ong27]

My 2yr old hen has this in her mouth. It's definitely attached - my husband tried to pull it out thinking it was a foreign body and a scab kind of came off and it bled a little bit.

She's currently isolated from the flock, in a crate with food and water. I put some iodine in her water to help heal the sore we made.

Her beak doesn't close fully so she's struggling to eat and drink.

Can you take a picture of the inside of her beak? Can she open her beak for you to look into it with a light? Is there any yellow material inside? Does her face smell bad? Is a vet possible? Do you think she may have been injured or pecked?
