A nice guy gave us some baby chicks that were a week old,on Friday for 4h project. But since we got them, they are more,lethargic than my other chicks. They get excited when I put food on paper towels and they run around for that but then curl up to sleep. My daughter noticed a few are shaking their heads a lot. He did have to drive almost an hour to met me and then I had to drive an hour home in cool wear, but heated car. Could it have caused an issue? What can I do?
