So, this morning I went out to feed and water my chickens, and I see a fox holding one of my black australorps by its neck! I chased it and the fox let go. The chicken was missing feathers but there were no gashes. The only weird thing is that its voice croaks. Like when your drinking with a straw and you finish the drink. It coughs every few minutes. I had to leave and I won't be home until 3. Will it be OK?
