I bought 4 new hens and slipped them into the coop at the end of the day. After 5 days they do not interact at all with my Rooster and 4 other hens. The origional group takes off as fast as they can in the morning when the coop is opened and spend all day out scratching and doing their thing, Then new hens don't go anywhere they just hang at the coop all day. The first day two of them went about 40 feet from the coop, two didn't even go out the door. Hopefully they will intergrate and start to free range with the other hens and the Rooster. This morning when I let them out the roo started to run back to the coop to strut in front of the new hens but they ignored him so he just ran off after the other hens. I may need to get a new roo for these hens as I am wanting to hatch eggs.
