Please help me my chicken is injured and I don’t know whether to leave her be so she can heal on her own or treat her.

This morning I woke up to check on my chickens and then I noticed my chicken had her face all beat up like if something attacked her.I thought it was my other chickens but there all in cages and none of them were hurt.So, I don’t know what attacked her or when it attacked her but I don’t know weather to let her heal on her own or treat her.

Clean up her injuries and apply an antiseptic/antibacterial poultry wound spray or dressing to her wounds.
She should be fine.
How many birds in what size coop do you keep her in?
Can you post pictures of your setup?

If there caged, that injury would be from a mouse or rat eating her face. This based on the size of injury.

Could she have spooked and smashed her face against the wires? Maybe a dab of Neosporin if anything looks very serious but she looks like she will heal.
