Hello, I have 3 grown hens that have been around each other for a long time and are the survivors of many predator attacks. Just 6 weeks ago got 4 baby chickens and quarantined them for 30 days. Then they were introduced to the flock during the day (my roommate did this. i would have put them in at night). Either way, the next morning after their first night in the coop/chicken run, 3 of them were killed. 2 were outside of the cage. 1 was dead inside (scared to death??) and there is one left alive and well and alone. I figured out what killed the 2 chickens, and it was because their first night they roosted on a little area next to the actual gate to the chicken run and from that spot a predator could walk by and literally grab them through the fence. They must have been pulled through or scared out. Since this has happened I have been making sure to train the other one to go into the coop at night which seems to be successful. I also let it free range from time to time, and those days it doesn't want to go inside the coop with the others or before dark, so I end up catching it and putting it in myself. Basically this chicken is by itself and I know that it is not good to have this, but his other buddies were murdered. What should I do? I have put the most aggressive hen in a separate cage and will leave her in there for a few days. She is isolated away from the flock. The other two grown hens still pick on Pants(its name) a little bit. So, Pants has been pacing back and forth a lot, and is afraid of the other chickens or at least steers clear. Seems to be eating and drinking fine but I feed it extra alone because I know it doesn't eat with the rest. Not sure how it will be when the big chicken comes back, but is there anything I can do for Pants or is she always going to be the loner? She is at least 10 weeks and 2/3 the size of the others, she is not small. Any ideas will help!
