I have 2 banty chicks, one is 4 days old and one is a day old. I have chick crumble but it seems too big still for them. Should i throw it in the blender or morter and pestal to grind it up more or let them figure out how to break it up more on their own? Right now, the day old isnt really eating yet but the 4 day old seems to fling out that which he can not eat easily. Thanks in advance
