I only have a small flock of 2. One girl, Mel, is around 6 years old, not sure on the breed but we are sure she has some buff Orpington in her. Our other girl sadly passed away recently. They were best friends and Mel was clearly sad after she passed. We thought the best thing to do would be to get a new girl, Tilly, to take Mels mind off things. However, it's not going so well at all. With our last girl, we introduced them and it only took them a couple of days to start dustbathing together and hanging out all the time. We did the usual and kept Tilly behind a fence for a few days and then put her into the coop with Mel at night. However, when they are let into the run, Mel just stands at the door and doesn't let Tilly come out. When she does manage to venture out for some food, Mel just pecks her and jumps on her back. I know that this has to happen to establish the order, but it doesn't appear to be letting up. I've tried distracting Mel but that only works for so long and she just goes back to attacking Tilly. They free range together fine, but never actually stand with each other and Mel will just occasionally run after Tilly. Does anyone have any tips on how I can help? I just want them to be friends, and it's heartbreaking to see Tilly being attacked every 5 minutes. Apologies for the long post!! But thanks in advance.
