I use 5 gallon buckets. My flock size is just a whisker over 30 birds. My style is to grab a bucket and head out the door with it. Obviously 5G is too heavy to want to carry it far. So, I carry it to garage door, and set it in my waiting wheelbarrow. When I come back, if the hose is handy, I fill the almost empty bucket 1/2 way with water, set it beside my feed barrel, and add the dry feed, give it a stir, and it's ready for the next time. I rotate 2 buckets. When I replenish one bucket, I also give a quick stir to the other bucket that is now 24 hours old. Only it's too thick to really stir it. I just punch it down a bit, kind of like punching down a bread dough. I leave the lids loosely set on top of the buckets. I am loathe to work any harder than I need to, so will not scoop feed into a separate carry container. You could simply use 5G buckets, and only fill them 1/2 way with your FF mix, or you might like the 3G buckets. I can get free buckets from the deli dept at my grocer.
