Buff Orpington-broody, pale comb, and being bullied

[jtrotter]

I have a Buff Orpington that has appeared to be broody. She jabbers non stop when I get her out of the nest inside the coop. As soon as I take her out, she comes right back in. When I try to make her stay out, she ruffles her feathers and talks non stop and the other hens start to peck her. Yesterday, they all started attacking her. Her comb is pale (before the attack) and they made her bleed. I pulled her and separated her from them. She is eating and drinking fine. Is this because she is broody or is something wrong?
