Sorry it didn't work out for you. Works for me... but I definitely agree about the dog food. My dog disliked it in short orderI did for over two years... for a flock of 82+.
It didn't save me a dime, nor were my birds healthier because of it. I no longer do it and think keeping a formulated ration formulated instead of attempting to alter what the experts deem good is semi ignorant on our part.
I wasted a lot of time and effort... though it was fun to see the bubbles and experience the changes that took places. I even tried it on my dog food, and don't recommend it!
If this is someone's route to save money due to waste.. I suggest using plain water and serve right away as standard mash.
Ultimately... all animals eat to fill their ENERGY (aka caloric) need. Yes, there is a fill up factor with regards to volume... but overall the energy consumption will be the same... according to my understanding.
