Is it safe to use turkey feed that has been stored through the winter?

[drew0301]

I have 3 bags of unopened 28% meatbird feed left from last years flock. I have kept them stored indoors inside of plastic and metal trash cans with lids. They have not been exposed to moisture and have not been infiltrated by any little creatures. The bags are in perfect condition and the feed does not feel clumpy or hard. Wondering if there is anything else I should be worried about that I haven't thought of and would like to hear everyones thoughts. Thanks so much folks!!!!

I'd feed it under those conditions.

Some of the vitamins will be insufficient, after all that time. Call the feed manufacturer about it before feeding, especially to younger birds. Mary
