I had to post the photography of Jack the rooster first. My bantie rooster, Romeo, was smaller but similarly marked. Romeo did not live up to his name. He and his spurs were on attack 24/7. So when I read about Jack and how he kept intruders out I thought, "Yep. I can totally see that. Weaponized enough. Territorial enough. Hoo Yah!"
I have enjoyed the "Voices of the First World War" podcasts. In this one "The Animals of War" specific conscripted war animals are shared through journal stories of UK soldiers and sailors. I agree with one, that the death of animals was horrendous, almost more than the men, as they had no choice, or idea, about what they were getting into. Over 16 millions animals served in World War I!
For more stories I suggest War Horse by Michael Morpurgo. Many of you are familiar with the stage adaptation of the book. Michael reads the audiobook if you prefer them as I do. Fair warning: Horse lovers will bawl their eyes out. The Lost Battalion, with Richie Schroeder, shows the amazing flights of carrier pigeons.
