Our Purina here is 13.75 as of last week. I've tried other brands but have seen a huge difference in the condition of chicks and the waste factor, so now I won't use anything else.
I also have a subscription to Poultry Press and get the 5.00 off 2nd bag coupon out every time. They expire in 12/08 but I am saving them for fall/winter so when my feed needs pick up, I can use them then. I like Poultry Press and it has lots of info on the different breeds as well as sponsors that have coops, incubators, tractors and everything else you'd want for your chickens. I'd get it even if it didn't have the Purina coupon but of course it's a plus.
I'm using a bit less feed right now because of all the grass and fruits/veggies available but I know it'll pick up soon enough.
