Of course, they're safe to eat... if you're planning on cooking them thoroughly. Oh, and not eating the uncleaned shells.
I can bet if you boil the eggs, even the shells would also make the shells edible as well. Not sure why you'd eat them. But....
Did they peel their eggs? I thought and then No of course not because they wouldn't have boiled eggs, they would have eaten them raw. If the eggs was small enough they would have just popped them into the mouth and crunched them up.
How did they do their toast?
excellent horsemeat sausage. Even better than venison sausage.
