How many eggs is too many?

My dogs are crazy about eggs. They would eat them everyday if they could. They practically do backflips as soon as egg hits the frying pan. At the moment they get a scrambled egg to share between the two of them about every 2nd day. I'm wondering if this is too much since eggs are high in fat? The rest of their diet is primarily made up of raw kangaroo mince which is very lean (nutritionally almost identical to venison) with a few raw chicken wings a week too. I don't want to take their treat away but I also know too much of a good thing can be no good at all - what do you nutrition experts think?
