Agree with others: freshness does rank high on buying feed. Always check the label for the mill date. Try to get it as fresh as possible.
also, store the feed in a protected area-not in direct sun, not exposed to rain. We store ours in an un-insulated barn in metal cans. We put one feed bag into the can, we do not dump the feed into the can, we leave it in the bag. So, it is exposed to the ambient humidity and cold,but it is always in the shade, so temperature fluctuations are gradual, and we do not experience moisture buildup in the can.
An adult bird will eat (on average) 1/4 lb of feed per day. So, 9 adult birds will eat 2.25lbs a day, approximately. So, you will get 20 days, or so, from a 50# bag of feed. You will go through feed faster if rodents are able to access your feed.
