I've been getting Sprout all-flock for awhile but recently learned that my local grain elevator makes their own Layer feed.. I looked at the guaranteed analysis and the % of protein/fat/ect is basically the same, except that the Layer's fiber is 4.0% as opposed to the all flock 8.0%. Also, the Layer does not list sodium. I compared the ingredients list (*eyescross*) and they have a lot of the same, though they do have some differences. The Layer ingredients sound more natural. The Layer feed has animal protein, while the all flock does not. And, the Layer is $4 cheaper. Is there any ingredients that I should stay away from? (Or look for?) Should the lack of sodium concern me?
