I got a pair of african goslings a week ago. Im smitten by the little buggers. Im wondering what adult geese eat? Right now they are eating a mix of flock raiser by purina and meat bird crumbles by nutrena. What do I need to feed them as adults? Also I need ideas on how to keep their water clean as adults. I plan on giving them a kids pool ...do I just need to dump and fill daily? Do they need a pool in the winter and if they do how do I keep it from freezing? Ive got chicken experience but geese are a new adventure and Im on a bit of a learning curve. Please feel free to offer any other advice you think I need to keep my birds safe and healthy
