'Shell grit' for chicks?

[kyuu]

I've given my 4 week old chicks some grass and a bit of oatmeal, but the pet stores only sell 'shell grit'
There is no nutritional information, instructions, only 'Shell grit, fine mix 2KG'... It seems to be made up of little different shells and bits. I'm just wondering, is this safe for my chicks? Because I've been reading about grit and it seems like extra calcium is bad for chicks
If this is so, is there a way to make my own grit for them by crushing rocks up? Or should I take them outside everyday for them to pick their own rocks?

Yes too much calcium is bad for little chicks. Hard on there organs. Kind of hard to tell about that product without all the information.
It has been suggested that you could use construction sand from the hardware store.

Imp- Good luck

I have been feeding my layers shell grit for 40 years with no problems.
I dont think baby chicks need it though.
