mama can and will take care of them...of course it is going to mean a lot more work for her but she will and its better than the undesirable trait being displayed by daddy at this time...they are all just about ready to fledge from what you say anyway so its ok...just be sure mama is given a little extra GOOD FOOD and calcium and protein to her diet for awhile...the babies will and should get this also...
get some ABBA EGG FOOD...(PETAMINE IS NO LONGER BEING SOLD in small quantity AND WILL GO ENTIRELY OFF THE MARKET SOON) and feed this for only a few months to mama and babies ...babies should have some till about 6 months of age...then dont feed it any longer to any of them as its very high in protein which in general is not good for birds HOWEVER that being said...they all need it right now for awhile...
here is a website for abba egg food they sell different sizes and the 3lb will be PLENTY..offer it in a couple of different food cups...not with seed mixed into it...this should be a preferred food for all of them right now.
