OKay, so I wouldn't worry too much, but definitely keep an eye on it. Is it eating and drinking well? Make sure it's not getting too hot, too. There is something that is stressing it... so see if you can figure out what that might be. Otherwise, it should go away in a day or two. Be sure it's not getting picked on, too.
it has been getting hot in brooder so tommorow im gina lower the heat and see if that helps
