Yesterday, all of my chickens were happy, running around together. Later yesterday, one chicken was freaked out sitting on my windowsill. The other two were hiding by a bush. One was missing. There were a few feathers, but barely any sign of struggle. We couldn't find her. All day today, I was sitting outside near my chickens. I was sure it was a bird of prey that stole my chicken. Maybe she had even gotten lost? But I needed to make sure there were no other birds around. I was on my computer, no predator birds in sight, I thought everything was fine. All of a sudden, I heard my chickens scream, two of them came running to me. I jumped up and made sure they were ok. My sister came out and watched them, my mom and I went to find my beloved chicken, Nugget(that is her name). The chickens were in the garden, only feathers left. I ran out of the garden, and I saw a line of her feathers, guessing she had been dragged. We only have two chickens left. I assume it was a fox attack, but I'm not sure. Any ideas of the predator?
