I have three hens and a rooster. Have had them since they were chicks now they are six months old. I bought three new hens the same age to add to the happy family. The new hens have been separated from the old with a fence so they can see and smell but can't touch and it has been two weeks. Tried to introduce and my rooster started attacking them and then the hens joined in. So back to the drawing board. What would be the best way to introduce them? I thought of taking all the older ones out of the coop and run for a couple of days and then put then put them back so they are new to it again,lol.
