I lost all but one of my hens to a raccoon attack. I reinforced their yard and added Nite Guard lights (so far so good). I purchased three new birds - two are 8 weeks old, one is 12 weeks. My coop is small - raised with a fenced in area on the bottom so the younger birds can come out and eat, drink and scratch. The original hen is outside of the coop during the day but within the yard so she can see them and interact. Each night I put the hen into the coop and everyone sleeps together with no problems, but as soon as I let them out in the morning, the original hen chases the youngsters and pecks at them (her beak is trimmed, so other than getting knocked in the head, the youngsters are okay). I keep separating them during the day. My question is: Will they ever get along? I'd like them to share the yard (the original group got on perfectly so I didn't think this hen would cause any problems)
