I feed Kalmbach 20% Flockmaker to everybody: Laying hens, roosters/cockerels, pre-lay pullets, turkeys, chicks. This keeps things simple: One feed bag, no feed transitions.
- I keep crumble handy if I have babies, and serve pellets if no small beaks are present.
- With freshly hatched chicks, crushing the crumble into smaller bits is possible if needed using your choice of kitchen tools.
- I sprinkle chick grit (aka "sand") on the crumble in the feeders and don't serve treats typically until they're ready to leave the brooder.
- Free-choice oyster shell flake is always available to layers and free-choice grit is always available, even though we free-range.
Yesterday I collected 15 eggs from 18 eligible layers, which is not a bad ratio given the makeup of my flock. All 5 of my ladies who will be 4 in July laid eggs, and I've got less-frequent layers like Marans and a turkey hen in the flock, so I'm pleased with this ratio. I've only lost one baby chick in my flock-manager career, a 2-day old Bielefelder who simply failed to thrive.
Do what's best for your birds, but I'm joining the chorus here encouraging folks to keep it simple.
