Hello. New chicken mom. My 3 week old white crested Polish black (Valeska) has her head feathers coming in and I think the other chicks might have thought it was food and started pecking at her poor head. This is my second set of chicks but Ive been lucky that none of them have been sick or injured so I need help. I have her separated and will be keeping her in the house with me while she heals. She is calling for her flock 
Here are my questions:

Here are my questions:
-
What can I put on her head to help her heal? - If I keep her in the house for a week, will her flock accept her back or do I need to do something special?
- Will she be too lonely being by herself? Will it affect her in any way?
