I am very happy to have found you! We have had 9 white longhorn hens for nearly two years with no issues. They are great egg layers and they have very spacious quarters. They are free range chickens throughout the day. All of the sudden without reason, two of the hens while out free ranging began to fight. One was injured and will recover but is being rejected by the rest of her flock. These girls are sister hens, born and raised together. Never any fighting? We cleaned her up the best we could. We need advice.
