G’Day from down under
Nurse Swicland 
Welcome!
I am so very sorry to hear of your loss
For you injured chicken, you should get some good advice on treatment if you post on the
Emergencies / Diseases / Injuries and Cures Forum. I wish her all the best.
For coop advice, I recommend this
Coop & Run Forum or you could also check out the
Predators & Pests Forum
I hope you enjoy being a BYC member. There are lots of friendly and very helpful folks here so not only is it overflowing with useful information it is also a great place to make friends and have some fun.
You might want to also pop in and say hello on your local thread:
Find Your State Thread
If you would like to share pictures and stories of your flock, you have come to the right place. BYC’ers never tire of these and do not back away slowly or commence eye rolling when the photo album or home videos come out
