it was post 12.Funny, it's post 15, not 12, and I have read all 4 pages before, and the people who posted that I trust, said oi feed formulated feed. I just feed All Flock which is an 18% feed. The mergansers will get some catfish feed during breeding, but that's it. A handful of scratch, minnows, crickets, etc occasionally for environmental enrichment, but that's it. I would like to feed Mazuri....it's the best feed on the market, and the only one which will give a COMPLETE nutrient analysis (AME/KG, amino acids, taurine, etc.), but it is about 4X All-flock because I would have to have it shipped in.
Want a balanced diet.....know the nutrient requirements of ducks....know what the composition of the feed you are using is.....know how you are changing the diet when you add something.....There are plenty of computer programs for feed formulation, unfortunately they tend to be expensive.
Just a note, all the time there are posts of leg weakness.....the immediate answer always given is more niacin.....no one mentions that the diet may be in-balanced with regards to Vit E and Selenium which has been related to white muscle disease, or capture myopathy. My an unknown mechanism, the in-balance makes an animal susceptible to tissue death when the bird is stressed. Causes a spike in several enzymes signifying tissue break down, and streak of dead muscle tissue, often in the heart and legs. Yes, I have lost birds to CM, and have published a case study on it.
