Hey, so I am new to owning chickens. I have done a lot of research, but I am having a little trouble figuring out how to introduce younger birds to older ones. I bought some Rhode Island Reds, ISA Browns and Barred Rocks at the same time, but my friend had some of their Bantam eggs hatch, I thought they were so cute, so I bought some off of him. Well now I am trying to introduce them to the older ones and I am having a little bit of a problem. I have been putting the Bantams in a run right next to the big ones for almost a week now, hoping that they would get use to each other, but I am still seeing the big ones pecking through the fencing at the Bantams. If anyone has any other ideas I would love to hear them. Thanks in advance.
