Layer feed or all flocks for non-mixed flock?

[Karlkurla Chooks]

Any Poultry Mix works well. My chooks forage in the garden as well.

There are several layer feeds that are 18-20% protein, so all flock isn't necessarily more protein. I always had to give calcium even when feeding layer. I have fed scratch daily in limited amounts for 32 years & haven't had a problem. Do what works for you! YMMV

Which layer feeds have 18-20% protein? I would like to look into it, thank you!
