We have chicks shipped express with heat packs all the time..not from them but from breeders.The heat packs work great and will be warm for days after you get the chicks so I toss it in the brooder with them when they get here.All hatcheries should offer express shipping no matter the size of the order.It's a huge difference with the chicks that arrive within hours vs 2 days.
