We got our first 3 hens (8 months old) in the spring & they have been fantastic layers. We get 3 eggs almost every day. About 3 weeks ago, we got 3 more hens. The were 8 months old when we got them as well. The 3 new hens had been laying according to the previous owner, but they've never laid for us. For the first week or 2, the older hens pecked at the new hens mercilessly. Now, they are much more mellow, but still keep their distance from each other. I realize that I didn't introduce them properly to each other, but what can I do now? How can we get them to produce eggs?
