I have calls... I was going to keep them on their 20% str for 6 wks and then i thought
a couple of them were maybe getting angel wing and immediately switched to 15 %.
Everyone on here said they switch at around 3 wks.... so I definately say u should switch
now.... and i feed greens everyday.... not sure about your other ? but someone will answer
dont worry

Starting Stage: hatch to 2 weeks=protein 18-20%

Growing Stage: Weeks 3 to 8=protein 15-16%

Developing Stage: weeks 9-20=13-14% protein

Laying Stage: three weeks prior to and throughout the laying season, the requirements for proteins many vitamins, and some minerals increase markedly. 15% protein is adequate, but 16-17% is often used. 18-20% protein will result in larger eggs. Calcium requirements jump to 2.5-3%

Holding or Maintenance Stage: Fully mature not laying12-14% protein requirement

Molting Stage: 15-16% protein for growing feathers.

I got this info from Storey's Guide to Raising Ducks, Dave Hollerread.
If you don't have it already, get it right away, this book is incredibly valuable!

From 3 weeks till like 20 weeks we feed ours Blue Seal grower Cal and everything seemed just fine.
Good Luck, and lower that protein!!
