Grit size for 15 week old chickens

[Fancypants1]

My chickens are 15 weeks old - should I change their grit to the larger size? They are still on chick grit.

I started giving my chickens regular grit at 8 weeks, as it indicated on the label of the grit I use. They are 14 weeks right now.

Great thanks - I am going to pick up some adult grit today.

Thanks!
