It's not your fault. These things happen. I am a first time chicken person and I was really stupid! I left the chicks alone outside and there was a rooster nearby and he could get in, but I thought,"He's fine he's a pacifist chicken and would never do anything," Well I was wrong, he got in and beat up our only hen out of our larger chickens. It's legs were broken(or so my mom said), so we moved it inside. We ended up having to put it out of it's misery. Lesson learned. With chickens and other birds you can grieve and feel sorry. I've learned that you just have to let go. I'm sorry for your loss.
