You might need a predator proof run. I have a hawk in my area and my ladies have a steel run with protection from above.
I am assuming your friend gave you instructions and supplies, so I am only adding this:
I give my girls mealworms in the evening. just a small handful, at bedtime.
This way they associate evening time with snack time and it is easier to get them contained.
I was glad I did, as one time I didn't latch the door correctly, and they went exploring the yard (remember, hawk!) so I ran out, grabbed the worms and they came running!
and keep a system with your eggs, 9 hens is a lot, depending on your family. They add up quickly! That is actually the biggest advice I can give you. Get the eggs organized.
They tell you a lot about your hens as well.
well ok, I think I lied.
I actually have 8 points of advice.
I wrote them down a couple of weeks ago:
