So I have four one week old chicks. I have thermometer inside the brooder that says 90 degrees. I noticed two always lay with their necks across each other's. The other two are off on their own. I worry because I'm always reading that if they crowd together it means they are cold. I just don't want to wake up to a dead baby. I want to make sure I'm doing everything correct. So is it normal for two to sleep like that or is it to cold?
