After weaning, I wouldnt feed free choice. What breed, sex, age of goats are you getting?
Creep feeding is a way of feeding so the babies can get to the food free choice but mommas cant. My creep feeder is a pen with a tiny door that only babies can get into so they can have their own food beause the big goats only get grain once a day the babies can have access all the time.
This feed is more of what I consider a "grain" I guess they are both the same really I just use the grain and chow to differentiate the two textures.
