You should ask yourself is the parent worth keeping? I have no other option but to hatch pets with Bad traits and would love to delete them BUT they are school pets and I would love for the school pet to give me something I can bebefit from in a fight. Like Hydra, I have three Hydra two are parents and all three are only worth deleting. I have two accounts and hatch between the two, But on both accounts both parents are not worth the treats I used to level them. They really should be deleted but I would love to keep the school pet but why? It does not benefit my wizard any. I have so many stormzillas running around it is not funny, and yet none are worth keeping or hatching with. I have been very disapointed with the pets in the game it is not funny. I have tried hatching as my rooms full of undesirable pets will show you. I have about decided that there are no good school pets with traits that will help a player. Made a mistake and hatched fire and stormzilla, I got a Heliphant gives a storm blade not fire blade but storm, I have no use for this. I need a Heliphant that gives a fire blade and stormzilla that gives a storm blade. So I stop mix hatching. I bought crown pets thinking maybe I would get better traits, Didnt happen, The Life Oni pet Balance gave me worse traits than my school Hydra had. I stop buying pets, and have about stop hatching because I can see it going nowhere. Dont tell me it takes time, I have all the pets in the world running around level up and none came out any better than those I hatched them with, I kept a book and tracked it I know what I am speaking about. This is why I am about to stop hatching and pet leveling I can see by my written records its going nowhere.
