My babies are 3 days old as of today. I went to the tractor store to buy meal worms (dried) and some chick grit. However as I was checking out I read on the chick grit saying that they have to be 2 weeks old. So this does mean I can't feed the meal worms or the chick grit to them until they are 2 weeks correct? I know they may have a bit of plain yogurt, but right now I don't have any on hand. What appropriate age should I start showering them with treats?
