This was my flock then. Most are in pix.
This is today.
I only keep them as pets. Give them treats and scratch.  I also do give all types of kitchen scraps to them. (nothing spoiled BTW, just cuttings from veggies and such, 

)  Now in winter, I will boil up a portion of Ramen Noodles  (without the flavor packet) and serve it warm. Its a feeding frenzy comparing it to Sharks with blood in water.

 I crush the noodles dry before cooking so chickens are not dealing with 16 inch long strands.  It is a really good treat at .20 cent cost.

Even though I don't seem to be feeding my chickens by the BOOK. (I call it science diet) and many here may criticize me for not giving enough of this and too much of that, my chickens LIVE LONG LIVES. Oldest went 13 years. I must be doing something correctly.  I may not win egg laying contests, but that is not my goal.  When my chickens do go on an egg laying streak, there are more than we  can eat. I give away to my neighbors. (only those that are not afraid of
 non store eggs)
50 pounds of Alfock seem to last me about 2 months.  I also do see squirrels helping themselves to the feed in the run as well.  I don't mind feeding those lil cuties as well. I have a soft heart for all living things. 

My squirrels trust me.

Your 50 pounds of feed will last your duration depending on how many mouths you feed. Main thing is to keep dry.  It will not deteriorate and expire for a good long time. (meaning, it is still eatable even though the nutritional values may have decreased a little, as does with all things)
Bottom line;; Don't stock up for the next 5 years.
