Today, I found one of my pet chickens dead in my coop. I didn’t know what she ha died from. I have lost several other chickens in a manner similar to this, however the deaths are usually several months apart. I found her under the ladder to the hen boxes, a very tight space, as well as I found no evidence of any wounds, and her comb and wattle showed no signs of frostbite. I want to know what I should look for as to determine the cause of death in a chicken, especially one who died like this. Also, this chicken was only ~2 yrs old.
