Sure you can! You could scramble it in a bowl, and put it in the microwave for 1 minute per egg and feed that to them too. Dont feed them the egg raw straight off the ground- I used to do that when I found a cracked one in a nest, I just tossed it into the runn for the hungry hens, then I developed 3 egg eaters- very bad news. I had to put them down after trying everything to break them of it. No one wants an egg eating hen. Mine would lay, turn around, and eat their eggs, but they NEVER did that until I started feeding them raw eggs from the nest in their pen.
Feed them the shells all crunched up too- its great calcium for them.
