NOT a pipe dream. Any effort to become self sufficient has many benefits. Less fuel to truck material from the mid west. Nutrients from land better managed to have good micronutrients. ( MIdwest is getting stripped.) Lots of options today to get seeds to see what you can grow. I am trying rabbits because I can grow enough of what they eat given a little time to learn how to harvest, dry and store.Yes, I had run across that bit of knowledge in my research. At this point, I only have monogastrics on my farm. However, my goal is to utilize all the resources my land has to offer and significantly reduce or eliminate outside sources...a pipe dream, I know...but I have the time and means to pursue it. If I find that my flock is not keeping good condition on silage (and possibly mealworms), then I will convert back to their current regimen.
Also, by the time I do acquire ruminants I will have had some practice and experience with the ensiling process.
Otherwise, just better eating of the chickens products. A pig farmer in VT buys hay from a local farmer to feed his pigs in the winter. A very remarkable enterprize to maximize the land to produce healthy food. ( sugarmtnfarm.com) He runs chickens with the hogs. THe eggs are fed to the piglets for more protein, and the hogs get to have the eggs the hens fail to lay in the nest boxes. He has planted a wide variety of forages. truely remarkable.
Ensiled grasses though are not fed. HOwever, whey and brewer grains are used. Maybe invest in a goat??
