We introduced 3 new hens to the flock approximately 6 weeks ago. They started in a brooder box in the coop for several weeks. Last week they were put into the coop with the other 10 girls. There is plenty of perches, but for the last 5 days, they perched on the outside of the coop in the secured run. There is still some pecking order going on and they have a safe area in the run. I have even put them in the coop after dark and found them back out in the run several hours later. They are 13 weeks old and I am not sure, but assume this will cause issues when they start laying. The other 10 are about 9 months old. I was thinking about making a door on the coop to keep them out of the run at night, but worry what kind of a feathery mess I may find in the morning. Has anyone come across this? If so any solutions?
