I have a small herd of 13 goats. One adult doe and the rest are wethers born this year. The pasture they are on used to have weeds and willows and birdsfoot trefoil. Within a week or so the weeds and willows were gone. The birdsfoot is still green and almost completely covers the ground. Each evening I take them out to browse different dikes where the browse is unlimited. We do this each evening unless it rains. They hate rain. I've noticed their rumens are smaller when I let them out and don't get quite as big when they are done with their evening meal. Do I need to start giving them hay in the morning or can I wait until their pasture is browsed further down? Is one big meal each day enough? The goats are going to be gone in late October and there really isn't a big enough are to move the fence. Thanks for the advice.
