So, I go to Winterhold to kill the Magic Anomalies with Faralda and Arniel, and I see a chicken being resurrected. I put my cursor on it and it said "Arniel's Chicken". I stood there for a sec to see if it would do anything, but it just walked around and chuckled. By then I was laughing so hard I had to pause the game.

Sadly, Arniel's chicken provided no help in defeating the anomalies.
