Hi, We had two backyard bantams. Unfortunately one died in November. With winter being so cold (Mass) we waited until April to add 2 more bantams. We added them (10 weeks old) at night, added extra feeder/waterer. The next morning the older chicken went bonkers, chasing and violently pecking at them. I added a divider down the run (we have an Eglu Go) so they could see but not peck each other. 2 more weeks have passed and the older chicken is still very violent towards the 2 young ones. We let them out every afternoon for a few hours and all day on the weekends hoping they could learn to mingle peacefully. No luck. Any advice on how long this will last, or if it's normal? Even better, advice on how to ease the bullying? Thanks in advance.
