Let me start off by THANKING all who have helped me with my first year of backyard eggs! Haven't lost a chick or hen. I will be getting some pullets this spring & I would like to know at what age to put the new pullets in with my laying hens? I have heard stories of the hens pecking the pullets to death. All of my hens get along fine with each other. I have a RIR who rules the coop, she's not mean, just lets the other hens know she is top hen. She is also the most friendly & loves to fly up into your coat hood & hang out with you. She isn't earmarked for the freezer yet as she is just a year old. No roosters to worry about as my city doesn't allow them.
