Last year (i know that this late to post about but I'm a new member) one of my red sex link hens was found inside the coop dead, and I have no idea what could have killed her.
We haven't had any other losses and she was our first loss.
I just wanted to know what could have killed her and that way I can protect my flock in case it could ever happen again.
Another few details are, that 2 of my other hens had a few scabs on their legs as if something had scratched them, I didn't really get a good look at the one that died because I freaked out, so someone else buried her, but he said that it looked like her thighs were bitten.
She was healthy before her demise.
The only thing about her that wasn't normal was that she had been debeaked and her lower beak had a small split and was twisting, despite this she was eating and drinking fine.
Also one of my BO hens was on the wrong side of their fence which has happened before so i don't know if that has to do with it or not.
