I feed mine the yolk,thats the part they like the most
.When I hard boil an egg they get half each,so I guess we can say that between them the have half a yolk each.Lady is 2lbs and Jess is 7lbs.
When I scramble eggs for them I do it with 2 eggs (and milk) and they share that,so sometimes they have 1 whole yolk each.. Iv never had a problem.
Iv never given them raw eggs though.
