last week i picked up 5 new golden comets, they said they were about 13 weeks old and i should be fine just adding them after dark. i ended up putting them in a cage in the coop with the others (red sex links and leghorns about 24 weeks) to let them get to know each other. i let them out after about 5 days and thought they were doing okay until yesterday..... the 5 little ones were hiding in the corner behind a bin. today i went out and one of the little ones had missing tail feathers and was dead and the others were pecking at her like crazy. the others were up on the roost huddled together. i took them out and have them seperated. what do i do now????????????
