When i had baby geese they loved eating spring onions, but we gave them the starter feed too and other bits of veg.
Really! Mine wouldn't touch onions of any kind. After two years of grazing my lawn the only 'weeds' left were wild onions or wild garlic. I tried to interest my geese in them but they would not touch them.
yeah. we cut them from one end in fine strips but not all the way along so they were still attatched at on end. kinda like a cheese string. they didnt really bother much with the grass we cut for them though.
