I have 3 hens and 3 pullets about 14 weeks. They are out in the yard together during the day and have been getting closer together, and in separate coops at night. The runs for the coops touch so they are aware of each other. Yesterday when they were outside, one of the pullets got stuck in a spot (I think when a hen chased her). I heard a commotion and went out and the hen was going crazy on the poor girl, and left her with a bleeding head. She's okay, and has been eating and drinking and is acting fine. I'm keeping the groups completely separated for now, but wonder where to go from here. I was hoping they could all be together for the winter for the heating but will I ever be able to put them all together? Any advice is appreciated.
