I didn't know a thing about raising chickens until about 4 years ago, I learned as I went. Didn't find this site until 1 1/2 yrs ago. I haven't lost a chicken to predators, but, I've been very lucky. We all must learn as we go, pick a tip here and there and try to do what we think is right. You've had a rough start, but, you'll get it. Tighten up your security and you'll be fine. Thanks for adopting those animals, takes a good person to do that... Good luck...
. Also now that you are down to just 2 another option is to use an easily made chicken tractor until !!Don't give up you can do it!!! Welcome to byc and there are tons of folks on here that can help and offer suggestions and ideas!!!
