Haha. My car makes the same noise. Except I would call it a high pitched horse sound instead of a chicken sound.
You have a bad bearing in the starter. The starter is failing. This usually only happens in cold weather when the engine is cold.
My Boxster starts up fine in Summer, Fall, Spring. It only happens in Winter time for me.
Eventually, the starter WILL go bad and you will know when that happens because you won't be able to start the car.
As for the idle. It could be MAF Sensor. It could be as simple as a dirty throttle body that you can clean yourself with alcohol or electric parts cleaner. It could also be a vacuum leak. Spray WD40 around the rubber hoses. If the engine runs better after you spray a particular hose, you found the leak.
