ok good to know as like i said mine never went for safflower and that i would cut back on or just give very very sparsley...(even eliminate) the barley tho ...id leave it ...not mess with that ...as sometimes they get in a mood for something (like us) and sometimes not...give her a chance to get accustomed to the need diet also ...just like getting accustomed to new surrounding when they first come home...
and remember (barley contains 92minerals and 22vitamins) to valuable to cut out ...for sure ...now is it the hullless barley and NOT THE PEARL barley...
and its about ...your on the right track...adjusting ratios...usually you want the two main grains to be the foundation and would have more of them in the mix...with about 1/4 to 1/3 of the extras added...
thats a good approximation...as your adjusting to begin with

(research the nutritional value of safflower see what it says) i havent used it in so long as they never went for it so i dont recall...see if its worth adding at all as your other grains may cover what safflower has in it .
