A pair of my budgies laid eggs and now they have three kids. and now they are like 23 days (not sure). And I have a budgie(name: tweety) and he is bonded with another budgie (not the parents I mentioned). One day he did something strange. He fed the budgie chicks even though he is not a parent. And the parents noticed it and got jealous I guess and attacked tweety in the head. and he hurt his feet. After like 2 hours tweety also attacked back. please tell me what to do??
