I have been giving my six "new" girls purina medicated chick starter. They are 15 weeks old and thriving. I went to TSC today to pick up layer pellets for my adults and asked if I could start the layer pellets for the teenagers and the woman said I could begin transitioning them to pellets. I thought I had some of the chick starter left and I was going to mix it half and half but found when I got home, no chick starter. Can I just give my girls layer pellets "cold"? Not cold cold but from chick starter to pellets with no transition? How about if I put the pellets in the food processor and make them smaller like the starter?
