help me choose a feed brand

I'm going to be trying a different feed for my layers but am totally not sure which way to go next.  We're currently feeding DuMor layer and i'm not 100% happy with it but here are the other choices i'm looking into:

-Purina Layena (told it's the same as DuMor)

-Purina Flock Raiser

-Blue Seal Layer

-Agway Layer

-Agway Producer (not sure if local store has it yet)

-Nutrena Layer (not sure which version local store has yet)

-Nutrena All Flock (not sure which version local store has yet)

-Keystone (just found out about a place that carries this)

I think if i can find it i'd like to try the Nutrena Nature Wise line of feeds.  I just found out there are 2 local placees that are Nutrena distributors but both are closed on sundays so i can't call them till tomorrow at least.  But i'm not really hopeful that either place will have it as i don't live in an area where a lot of people are into raising their animals more naturally.

What do you all think?

I'm paying just over $13 a bag for the DuMor right now.  Agway isn't any better either.  So that much doesn't bother me.  I'll have 30 hens and 4 rooster on it come fall but will just buy several bags at a time when we get to that point.  If i end up on All Flock i'll also have 10 ducks added to that number and willprobably buy a palett worth at a time then too if i can find a way to store it.

I called around yesterday and the Nutrena dealers only carry the "country feeds" version.  Noplace has the "nature wise" version. :(

I did find out that TSC is carrying the Omega-3 Layer now.  So i think i'm going to try that.
