Yeah, I have always used those plastic kitty litter tubs for my feed because I can carry them out to the coop easily. And, I have one of those huge white drums from Concord Feed for my cat food. (Cats have an auto feeder, so I only fill it once a month.)
Luckily, the cat food was almost gone, so used that drum for one of the bags, and filled all my kitty litters tubs. The rest went in the feeder in the coop. I don't really have room to keep so many plastic bins, though, so will not be buying bags of layena in bulk again.
Now, hopefully I can eradicate the rodents from the garage. There are five pianos in there. I hope they don't get damaged.
eta - Jeremy, I tried switching them to pellets once, and they actually stopped eating, and then stopped laying in the middle of summer. The vet said birds are visual eaters, and didn't know it was food. I waited too long to try it. You should really only switch them when they are young (POL), or when another bird shows them it's okay to eat it.
A 50-lb bag of crumbles lasts me about 3 1/2 weeks for 6 birds. That doesn't seem too bad to me.
