According to Kikar, an interesting, and weird, incident happened at a Kapparos location in Jerusalem.

A family went to do their annual kapparos with a chicken ceremony. When performing the ceremony over the 1.5 year old son, immediately after saying the phrase "this rooster will go to its death", the rooster died in their hands.

The father freaked out a bit, as anybody would, and went and replaced it with a different rooster. Upon performing the ceremony again the same thing happened a second time - the rooster died in their hands immediately after saying the phrase "this rooster will go to its death".

As they say, third time is a charm. The third set worked and the rooster did not die until they killed it.

Afterwards the father went to his rav to ask what it all signifies, if they must be concerned. The rav's answer was very rational and instead of saying he has to do tshuva for something or it shows someone was meant to die, God forbid, but received forgiveness, or anything like that, he railed against the kapparos ceremony as performed today saying it is prohibited to do kapparos in the street, the chickens are left in the heat and not given water to drink, they are left outside in the heat for 15 hours, cages on cages... it is tzaar baalei chaim..

Either way, it would freak anyone out...
