YEPPER!! Just like using one on a human.. in the way that it amplifies sounds! You can hear the little pips! If they are doing it.Really - a stethoscope works?!? Heartbeats or movement? Now I wish I would have grabbed mine yesterday before heading home.... have 3 I'm still waiting for in my incubator, and 8 in the brooder (6 BCM and 2 EE).
