I am a newbee and have 6 hens and 2 rooster that are 7 weeks old and in thier run. I also have 6 hens that are only 3 weeks old and still in the house. Should be combining the two groups in 2-3 weeks. Any advice? Worked to hard to see them not take well to each other. Everyone is still very young. Would love to hear from you on this.
