I just checked my flock of 8 chickens (1 rooster 7 hens) and found one of the hens dead in the coop. I'm surprised since I've been out there twice today and none of them were acting unusual. Any reason why one could just drop dead? One thing to note, I have noticed some loud noises during the morning which I just chalked up to hens laying since I'm new to this and they're new to laying. Maybe it was this hen in distress? I'm at a loss. Looking for any insight.
