So I have 6 pullets, all 16 weeks old, together their whole life. They are all starting to really establish pecking order but it’s mostly harmless chest bumping. However, the largest is starting to bully the smallest bird whenever their are treats. She doesn’t bully anyone else. The smallest Bird is a black Australorp but really small for her breed, just a small bird I guess, seems healthy. It only happens when treats are involved. The small bird is usually able to get some but will get chased by the large bird with increasing frequency. The small bird does get to eat and drink. Anything I should watch out for or do? Also wondered if som how I misidentified the breed of each as she is a lot smaller than the other black Austrolorp. I thought the biggest was the Saphire Rock I got as she looked different from the other two (austrolorps) I got.
