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? They do eat Mazuri waterfowl maintenance. Thanks!
