I don't really think it's appropriate to criticize the OP with out further information. While some of us are well prepared for the new animals we embark on not everyone is. For all we know the OP could have had some dropped on them and are just trying to take care of them. I personally would prefer someone post on the forum asking questions on how to properly raise their animals than them assume how to raise them and end up doing more harm than good. As for the original question people can feed a variety of layers crumbles, pellets, veggies, insects, and some choose to feed the occasional table scrap. However, if your birds aren't free ranging you may need to supplement grit.
