Yes... my 2 wk old chicks are scared to death of a tee tiny lil ole fly.. lol. When will they learn that it might be good to catch and eat??? One had gotten in to their brooder and you would have thought it was the end of the world. Poor babies.
Chicks start out scared of everything. My sister thought it hilarious that they ran away from the tiny red dot of a laser pointer. Eventually as you begin to feed them stuff besides chicken feed and they try out a few bugs for themselves they will start to see every dot and everything that moves as possible food.
I let mine "freerange" after about a week outside under some supervision and they started eating ants. Just put them outside...they'll calm down.
They have been outside for one outing.. tryin to find time for another.. lol I dont see the evil fly anymore so maybe he made it in to someones tummy!
