I currently have 3 1yr old RIR hens and recently added 4 EE and 4 NHR which are 6 weeks old. Temperatures at night are around 67-72 and during the date 75-85. I have the pullets in a fenced in area near the coop so the hens can see them and have been doing this every day for about 2 weeks. Now the Pullets are outgrowing the large tote in my garage that I have kept them in at night. I decided tonight to place them in the nesting boxes in the coop with the hens. I placed them in at dark so their was no problems. I plan on waking up before sunrise to check out how everyone made out through the night. Any one else introduce pullets to their hens this way? How did it turn out. I am a little afraid of what I might see tomorrow morning. I have heard horror stories.
