About 3 weeks ago, I got two hens for my 4 month old rooster. I set up an area connecting to his for them to get used to eachother. The problem is, he still is trying to hurt them and attacks them when they're together. I have a great chicken coop area with 6 ft fencing to prevent escapes. However, these hens keep getting out of their "jerry-rigged" small area and I spend all day chasing them out of the neighbors field. I need to find a way to get all three living together in peace and safety. Oh, and the hens aren't laying eggs yet...but they should be very soon. What do I do?!
