Shes doing a fantastic job as both a mummah and as a pet! 
she could of just looked after the bestest and neglected the other but no, shes looking after the other two and making sure they grow up big and strong for daddeh!
As for the Ugwy poopie one… if its ugwy its gonna use up resources, its gonna make the whole group look unsightly, daddeh woudnt want his best pets looking off because of one bad egg, shes a excellent mummah and pet tbh, she would make a good breeding center sorter.
