Broody hatched one egg and then abandoned the nest. I took the eggs she was sitting on and put them under the another broody 2 days ago. I went out to collect eggs this morning and found one buried under the pine shavings in an empty nesting box. I was not really paying attention so I took them all in to rise off, when I noticed that one of them had a faded black mark on it. I thought it was a speck so I was trying to scrub it off and it was shaking when I felt the body move inside the egg. I immediately stopped washing it, and ran out to put in under the broody again. Did I kill the chick by shaking the egg? I could clearly hear the beak or head hit the side of the egg. I wanted to add the the temperatures around here have been in the 90s with high humidity, and the nights have been about 70 degrees.
