I feed Kings Brand waterfowl pellets. Been using it for years. I am in central California and it is milled just south of me. It is what Metzer farms uses. Great stuff, and only $16 a bag.
Absolutely, mine are a lot friendlier than other breeds I have had. They may hiss at you during breeding season, but mine will not chase you like other breeds.
I love them all, and have raised most of them. I really like pilgrims to, but the Dewlap Toulouse are the calmest and the most entertaining geese I have been around. They act more like a dog than a goose some of the time.
