Layers pelletts rejected

Newbie!! Bought 3 POL ISA Browns 10 days ago and they wont eat the "Countrywide" layers pellets I've bought from local animal feed supplier.  For fear of them starving I've given them mixed corn and scraps later in the day - but the pellets are flatly refused.  I've tried mixing them with other things - no luck.  Have others had trouble with this brand?  What brand of pellet is recommend that will get them eating?  Help please!

Yes - I did ask the breeding farm and they told me they bought their pellets in bulk and weren't sure of 'brand'.  They did however say that they once bought pelletts from a cheap and cheerful supplier nearby and their chickens wouldn't eat them either.  Evidently my new birds were on pelletts and not mash when I bought them.  I thought I may go for something special to tempt them - but I'm not sure now you tell me that others have experience of the organic pelletts you use also being rejected.  Think I may go off to the feed supplier and have a word and perhaps get some 'samples' of other brands to try!! Gosh -  I wasn't expecting picky chickens!!!  But I do want healthy happy chickens 

They'll eat it if there's nothing else. Stop giving them scraps and corn and they'll eat it 

Thank you everyone .... guess I'm being a bit over anxious .... so now I'm being mean and haven't fed them any extras today.  I did get a small bag of some different pelletts to try from my feed supplier this afternoon - but they've turned their beaks up at those too.  It's a battle of wills!!

You could try a little Poultry Spice with the pellets.
