I no longer have the bag of feed to tell you the % of protein in the starter. The barley and oat is 16% The grower is also 17%.
But I do know that is why I mix my feed...Mine only eat a bit of the grains each day. They eat mostly the forage, fruits and veggies.
I was told to think like a Duck...
I was taught to feed Ducklings/Ducks this way....Never gotten Angel wing.
Duckling starter or unmedicated chick starter mixed with scratch grains, oat and barley crumble. till 8 weeks
