It's odd that thing would work when I couldn't hear a thing with my (professional) stethoscope.

WOW that is surprising! wonder why not? you'd think the stethescope would be a piece of cake to hear them. all i know is the chicks sounded like they were playing the drums when i held it to the eggs! LOL

What day of incubation did you listen for the heartbeat? How many days is your incubation period?

it was for coturnix eggs and i didn't think to check until hatch day (18) when i saw there was some trouble with chicks and a friend suggested i check the temps with a new thermometer....
