Hi I'm new and have chickens pig and ducks. And of course our dog. And several eggs in the incubator. Imy first egg started. Hiring yesterday and after ready about hatching eggs I didn't want to help it. And now I think k it is dead. It isn't moving or chirping. I took some of the shell away to see if it would move and if it was breathing a. I don't see any movement. I see yellowish stuff but no blood. Dhow do you k ow for sure it is dead? Or is the simple fact that it isn't moving or chirping anymore the answer it is dead? Pls help
