Getting ex-batts to eat pellets

I bought a cheap bag of crumb for my new ex-batts, till they get used to the BWHT layer pellets.  The daft chickens devour the crumb like it is a  treat and ignore the pellets.  Do I need to buy them more crumb or  can I just leave them with the pellets?  (I've had the chooks since last sunday.)

I only did it the once, half crumb half pellet, next day pellet, they figured it out soon enough.

i would think its the same as introducing new diet to most animals or even a baby
do it gradualy over a week say ,adding more of the new food each day
so as not to upset their system

Exactly.
