So I have a tiny flock of 4, now 3. They were hatched October 21st 2011. The Rooster was overly aggressive, always chasing and headbutting my children. A friend at work needed a 2nd Rooster, so he came and picked him up this morning. The rooster was the obvious leader of the three hens. Will the hens adapt to the new arrangement? When could I add a few more hens? We have a 4X6 Coop and the birds are free to go as they please. Thanks for any insight.
