Does anyone else grow fodder for their geese? I currently give mine wheat and barley fodder as a treat, but I'd prefer fodder to make up the majority of their diet as I feel it's much healthier/natural for them. But I'm worried they could end up missing out on nutrients, is there a particular blend of seed or way to ensure they are getting all the nutrients they need?
It's been a long time since I raised ducks and geese. Geese are particularly good at eating grass. When I had geese, I allowed them to free range on my lawn, and more importantly, I live on a lake and they were in the water a lot eating stuff. I always had commercial feed available for them, but they showed more interested in eating grass and lake stuff. They did not eat much commercial feed, but it was always offered. I don't know what nutrients commercial feed offers that the geese could not get from eating plants, but wild geese seem to grow strong and healthy without commercial feed pellets.
I am raising chickens now, and the commercial layer feed I give my birds contains oyster shells, which is something I don't believe they get from fodder. However, barley fodder contains 16.7 protein, which is almost exactly what my 16% protein commercial layer feed provides.
As to fodder nutrients, I am no expert, so I will offer this
Sprouted Barley Fodder Fact Sheet by The NY Farm Viability Institute. What I find interesting in that barley fodder fact sheet is that the vitamins in grown fodder far exceed the vitamins in the barley seed itself. The other thing I keep reading about is that the birds are able to digest fodder and extract nutrients from the grass much better than eating whole grains. I don't know if that holds true for commercial feed, which is ground and pelletized grains. Also, fodder is as much as 95% water by weight, so 1 pound of fodder is not the eqivalent to 1 pound of whole grain.
I give my 10 chickens a half dish pan bin of fresh barley fodder every morning. It is used as a supplement to their layer feed, and not a replacement. But my chickens are laying eggs, it's in the middle of a Minnesota winter, and there is no other options for fresh green grass for my hens. They love the barley fodder and eat that before their commerical feed. I grow the fodder to give my girls some more natural, and healthy green options to eat. There will be no fresh grass to eat for months where I live.
