2 cents.  Yep, here's my two cents.
I have also adopted chickens with severely cut beaks.  I noticed that they couldn't do crumble well.  They all had issues with weight, feathers, eye sight, mites/lice, etc.  (The chickens have been here long enough that I know their beaks are never going to grow back.)
At the time I adopted them, I was doing crumble and pellets (organic, non GMO).
I switched over to fermented feed for everyone -  the chickens, the ducks, and the turkeys.  After doing it for a bit, I felt that I needed to take a time out and hit the reset button.  I posted my questions on BYC.  
* I have 4 five gallon buckets of fermented feed going at all times.
* the amount of feed I go through varies, depending on a lot of factors.  I may go through one bucket or I may go through three buckets of feed in a day.
* I also have multiple flocks, multiple food needs, multiple feeding stations, rough terrain, not so easy to access pastures, and a lot of animals!  (Yes, I am still open to providing forever homes to more animals that need it.)  
* I buy 18% or 22% protein feed, depending on what is available.  
*I buy various other things, like oats, legumes, etc to feed the animals.
* In the five gallon buckets, I add water from the tap (I have a water softener and a black light/UV filter system) and I add feed.  
JUST feed.
----  When I use pellets, some stuff settles, some stuff rises to the top.  The pellets puff up.  I stir two to three times a day.  Pellets seem to make more feed than crumbles BUT my guys seem to be hungrier on the pellet fermented feed than the crumble feed.
----  When I use crumbles, the stuff sinks to the bottom and becomes a heavy sludge.  This is where stirring is so beneficial.
----  I stir before I scoop out the feed using a 4 cup measuring cup.
*  In separate, large tupperware containers, I soak the oats, the legumes, and everything else dry I am giving the animals.  I scoop that out using a one cup measuring spoon and put it in the food dishes/food containers.  The stuff doesn't get moldy.  Sometimes it will ferment - get bubbly.  I go through it fast enough that fermenting seldom happens.
* I currently have ten feeding stations.   The places that are easily accessible to me with an easy walk, I put the feed (goodies plus fermented feed) directly into the food containers and take it out.  The places that are not easy to access or are a bit of a walk, I put the food in plastic containers with lids and delivery that way.  MUCH easier than how I had been doing.  (I so needed to hit the reset button to work smarter not harder.)  --- I deliver the food in the morning BEFORE I let the animals out.
*  The feed doesn't really smell.  Yeah, there's a warm yeasty smell sometimes.  Once, and only once, there was a bad smell.  I was the only one who could smell it.  When I hit the reset button, I washed all the buckets out and let them dry before starting again.  I do not wash the buckets in between batches.
* I always leave a little feed at the bottom of the bucket to help the new batch get going.
* I cover the buckets with dish towels.  The flies still manage to get in and drown when I take the towel off.  That's ok - extra protein.  
* I use to go through 35-40# of dry feed a day.  I have more animals now, bigger and older now, than the dry feed days.  I go through a 40# bag of feed in about 2-3 days now.
* I supplement the feed (as I did before) with oats, legumes, rice, etc.  I soak all the dry stuff separately!  I also supplement (as I did before) with fresh fruits and veggies.
Stir the feed BEFORE you scoop it out.
Soak the grains/seeds separately and mix into the food container.
