I am expecting a flock of 9 ducks and 2 geese next week, and have already bought the Mazuri starter feed for them. I’m worried about the high protein and when they should be switched to a lower protein food. I was originally planning to feed them this starter food until they are transitioned to maintenance at 8 weeks, but I’m worried the high protein will cause angel wing. My other idea is to feed Mazuri for the first 3 weeks which is 20% protein, then change to Kalmbach duck & goose food which is 18% until they are 8 weeks. Does anyone have advice on if this is necessary? When do you transition duckling and goslings off of Mazuri starter?
