little one keeps getting beat up

[flockitup]

A week ago I traded three birds off they were roos. When I got home i noticed my barred rock was hurt i think from the fruit box i used to transport the chicks. Her comb was scraped and bleeding very little. I held it dabbed it with my shirt yet no crimson but i could tell it was a fresh injury. i decided that since she wasn't bleeding i could just throw her in with the rest of them and she would be fine. nope the next morning her comb was torn more and i witnessed them pecking her. she has now been separated a week and all healed up and the flock is now coming up to attack her as soon as i put her in the pen. what do i do?

I would try to integrate her slowly.. Chickens have a very short memory span so they have probably forgotten she is one of their own.. I would put the injured hen in a run or cage where the others have to see her but cant harm her then aftera few days late at night integrate her back onto the roost hopefully in the morninig all will be peaceful...
