I have an Australorp Rooster and Hen that are 9 months old and 6 Barred Rock hens that are 6 months old. They have been in separate pens with hardware cloth between them so they could see each other for about three months. I tried to put them together and the first day the Rooster was patrolling and guarding the food and would not allow them access to the food. I put a separate feeder in the coop that evening. The next day the Rooster had backed them into a corner of the coop and would not allow them to access either feeder or the water. At that point I separated them again. Is this normal behavior for a Rooster? Did I try to put them together too soon? I thought he would be excited to have more girls. I expected some difficulty from the hen but, nothing like this from the Rooster. Do I wait a month, two months and try again? Should I wait until the Barred Rock hens start to lay before I try to put them together? Any advice would be appreciated.
