Kylee, If I might suggest, contact your area state agricultural agency and ask them what would be a good planting. Stick to prairie grasses, forbs, and legumes that are indigenous to your area. Many times we are sold the latest and greatest seed at the feed & seed store without a thought as to whether it will do well and thrive OR our goats will eat it. Also keep in mind that goats are browsers and like a variety of foodstuffs. Right now my goats are eating acorns like they are going out of style in the mornings, having a siesta, then going into the pasture and eating pasture stuff to balance out their diet. With a stop at the protien tub and minerals in between. We plant bahia grass and sericea lespedeza for summer, clovers for spring, and purple topped turnips and austrian winter peas for well, you guessed it, winter! BUT that is what grows well in east-central Texas, not Washington state!
Set up your pastures/paddocks for rotational grazing in order to allow for parasite help and grazing management. IT WORKS!
Good luck, and please do your research!
