I only do if mine are cracked. I only had one like that so far. I just wash outside of egg and crack in skillet. Just turn in nonstick pan with spatula. Don’t add anything not even oil. Voila scrambled eggs! I place in disposable cup to take out to feeder and dump in. Chickens loved the warm treat and they do not egg peck as result. Frozen egg before scrambling. It thaws in pan. Looks like normal fluffy scrambled eggs when done.
You could also boil it as a treat and they come out fine.
