I had 6 chicks and two turned out to be roosters, so I found them a new home. I have three ISA browns and 1 black australorp. I went out and bought a new hen (BUFF orpington) who is about 16 weeks old. Being new to chickens and not doing research I just added her to the group and they immediately began pecking her. I separated her and did some research and realized I made a mistake and am not sure how, if at all, it can be corrected. During the day, we have kept her in the coop in a partitioned area. At night once they have all gone to roost in the hen house she flies over the partition we made and goes into the coop with no incident. We let them out in the morning and the other hens (two more than the others but will all join in when it starts) will start attacking her. So we are keeping her separate during the day. I tried putting a thin layer of Vic's vapor rub on her neck and shoulder area but it didn't seem to stop it much and I separated them again pretty quickly because I felt so bad for her. I'm considering putting the most aggressive one or two in the partition and then letting the new one with the others to see how that goes but don't want to make any more mistakes than I already have so I figured I would ask her how to pursue first. I really don't want to have to get rid of my new hen but don't want them to draw blood. HELP!!!!
