I love my birds as well! None of that crud!The feed we use only comes as a crumble, and it works for the chicks right on up, so it's handy to only have one feed everywhere.
Agree that there's usually less waste with pellets, but not fine for the chicks.
Once we tried a local mill's mash, and it wasn't that good a feed, so haven't done that again.
Would never use a whole grain feed here.
