I went to feed my flock tonight and I found one dead, the rooster has two swollen eyes and one of the other hens had one swollen eye. I really don't know what could have happened or what to do. Is there any way it was an attack? I mean, theres no breaks in the coop or holes of any kind and they were fine this morning. I'm new to owning chickens these are my first, any help? Please and Thank you!!
