Hello Wordman
I too am on a 'Limited" food budget.
If you are close to a metro area as I am.
I hit the grocery stores and pick up the "Trimmings" from the Produce Department.
Cabbage Leaves, Carrot tops,Beet Tops, ETC.
When in season Sweet Corn Husk that people "Shuck" and drop in a trash barrel.
As long as the "Greens" are not spoiled goats will eat them with relish.
My horses LOVE Sweet Corn Husk and in many cases people that pull a good chunk of husk off a ear of corn and don't like the "LOOK" throw the whole ear in the trash next to the sweet corn display. I have come away several times with enough sweet corn to cook up for a good meal. As well as a couple bushels of fresh husks to feed the horses.
NOTE: All of the above you need to feed and portion out ASAP because of spoilage.
But your critters will love it and if you play your cards right it is "FREE" feed.
Best Goat food is weeds and underbrush unless you are milking.
In my case here the boys have lots of underbrush even in the winter to chew on and get a couple small cans of Alpha pellets a couple times a day. They do stick around BC1 with no fence up and come running when called in. Of course there is a treat for them when they respond.
Goats are easy and "Smart" enough to be bribed to do just about anything.
Happy Trails
