You could say there's three seasons, winter/resting is one breeding another and racing the other. No two seasons do you feed the same, by that I mean the same grains are fed but in different proportions. Winter you would feed a higher proportion of Barley, breeding a higher proportion of Tic Beans or peas, racing a higher proportion of maize. I would suggest you buy a good breeding mix as a base mix along with a bag of Tic beans a bag of Barley and a bag of Maize and add these to the base mix as the seasons dictate.
