I would like to pick up some chicks in-person this coming February (I'm a planner!), instead of having them mailed and having to wait until April. I will only be picking up 5 and the hatchery is about 3 and a half hours away. Will the chicks be okay in a box that long? Should I put them in the passenger seat with the seat warmer on? I just want to give them the best start possible and don't know if they need some sort of warming device or something. They would be hatched the same day I pick them up, if that helps. Thank you!
