Each morning my DH lets out the chickens before work and then I take care of them in the evening. Last night after I had refreshed the food/water and was bringing them in, I found one of my roo's tangled up in netting and laying on the ground. His head was swollen and bare-all the feathers were plucked out. His eyes swollen shut and his comb was literally half torn off of his head. I have no idea how long he was there but I am sure it was the other roo we have that must have chased him and attacked him. I did my best to clean him up, medicate him and warm him up. He was bloody, full of mud and gasping for air. I have a feeling he either inhaled or swallowed some dirt/mud. He was a banty roo about 4-5 yrs old. Can anyone venture a guess as to why he died? I am thinking maybe a strain on his heart or he really did swallow mud. Thanks.
