Will my birds babies be sickly?

Question
I have a Female Lutino who mated with my Fischer Lovebird Male.  The Eggs hatched and the babies are doing good so far.  Is there diference in species a problem?  Are they what they call Mule's?  What are the rules, cause I also have a Peach Face and A Black Masked mating and laying eggs? Thanks

Answer
Oh the clubs and organizations really frown on this sort of breeding as do I, You should have paired the types with there related types instead of making "mulkes" the babeis should be healthy and fine but they will not be worth much money when sold and whoever you sell them too should be told never to breed them as they would only be further making "mutt's"
