No but thought doing that. Wasn't sure if a float test works the same for viability of chick as it does for eating purposes (if that makes sense). What temp water so as not to cool them? I assume do it as quickly as possible considering the humidity matters and this would be 100%!
Yep, strange, isn't it? Just make certain that there are no cracks/pips in the eggs otherwise they would drown. You would want the waster to be at about 100 degrees so that it's the same temp as the egg. If it floats, it's a dud if it's towards the bottom with air cell above water and rocking it's alive. you would have to make sure you let the water have time to settle from sitting the eggs in. If any movement at all I would consider them alive. Hope this helps!
