Fallen Comb

[Buffy Orp]

I have a RIR whose comb just suddenly flopped over. I noticed when a number of the other hens were jumping on her and pecking at her comb. Now she is petrified to leave the coop and I find her every morning and night in one of the nesting boxes. she doesn't seem sick, she is very docile and lets me handle her but I am afraid she will just fade away if she doesn't get outside and walk around. Any suggestions?

Is her comb a normal colour?
Does she have access to water?
Pictures would be good...
Is there any way that you could crate her within eyesight of the rest of the flock, so she can get some sunshine while you figure out what's going on?

her comb looks blue from where the other hen pecked her, like it's bruised. she comes out of the nesting box a little more until the one Buff Orp goes after her. I check her every day and keep food and water just outside the box where she hides.

Check her for mites and if you are confident that she is not sickly, check this thread regarding bullying https://www.backyardchickens.com/t/288038/separate-the-bully-or-the-bullied
